Komodo IDE/Edit Release Notes

Welcome to Komodo, ActiveState's Integrated Development Environment (IDE). These Release Notes cover what's new, detailed changes and bug fixes and known issues for Komodo IDE and Komodo Edit.

What's New in Komodo IDE/Edit

5.0

• Built on Mozilla 1.9: Komodo is now built on the Mozilla 1.9 branch, the same code base Firefox 3.0 is built on. This includes a number of bug fixes and performance improvements, and provides a more platform-native look and feel.
• Multi-Window: Komodo can now open multiple top-level windows, allowing you to configure your workspace the way you want when editing or debugging.
• Improved Tabstops: Tabstops in snippets and file templates are now more intuitive and flexible.

• Mercurial, Bazaar, and Git Support: Integration support for the Mercurial (hg), Bazaar (bzr), and Git source control systems.
• Code Formatting: Configurable commands for formatting selections and documents.
• SCC Checkout: A new interface for checking out working copies of a repository from within Komodo.

Detailed Changes and Bug Fixes in Komodo IDE/Edit

Changes related to debugging, interactive shells, source code control, the HTTP Inspector, the Rx Toolkit, the Code Browser, and the Sections List apply to Komodo IDE only.

5.0.2 Bug Fixes

• Fixed settings import from previous versions when KOMODO_USERDATIDIR is set.. (Bug 80768)

5.0 Bug Fixes

• Key binding changes: Moved the debugger's default step over keybinding from 'F10'/'Ctrl'+'F10' to 'F12'/'Ctrl-F12'. Toggling the interactive shell has moved from 'F12' to 'Shift'-'F12'. (Bug 80296)
• SCC: fixed bzr incorrectly showing non-scc files as being under scc control. (Bug 80431)
• Fixed file type not showing up in the status bar after opening or creating a file. (Bug 80462)
• Projects: Moved the "New Project", "Open Project" and "Save Project" buttons into a "Project Tools" menulist to make more room for the filter box. (Bug 79625)

• Keybindings: Reordered keybindings so common shortcuts appear in menus. (Bug 80530)
• Fix non-ascii character handling in replaceTarget (indent region, comment/uncomment region, vi-mode replace, spell check, find/replace). (Bug 80511)
• Sped up parsing of long lines of JavaScript and HTML. (Bug 80496)
• SCC: Less CPU intensive mercurial status checking. (Bug 80563)
• HTML: Changed default tidy linting to not include accessibility checks. (Bug 80598)
• Remote Files: Fixed "File|Save Remotely As..." not working for untitled (new) files. (Bug 80605)

• OS X: Fixed 'Cmd'+'W' close behavior for the Preferences dialog. (Bug 80619)
• JavaScript API: Added simple API for clipboard operations. (Bug 79772)
• JavaScript API: Added the xtk namespace to the API documentation. (Bug 80646)
• Windows: Fixed hard crashes. (Bug 76066)
• Calltips: Added preference for maximum number of lines shown. (Bug 70560)
• PHP: Statically typed function arguments now correctly parsed. (Bug 79003)
• Common application directories now added to the PATH in Komodo's user environment settings. (Bug 80656)
• Vista: Fixed menus appearing with a vertical line through the text. Extension authors must update usages of <menu class="menu-iconic-wide"> and <menuitem class="menuitem-iconic-wide"> according to these rules:
  • Drop custom 'menu-iconic-wide' and 'menuitem-iconic-wide' classes/bindings in favor of the Mozilla toolkit 'menu-iconic' and 'menuitem-iconic'.
  • Use these classes only if your menu/menuitem has an icon. Otherwise the alignment of the menu/menuitem labels will be incorrect in context menus on Mac OS X.
  (Bug 80629)
• Debugger: Starting a remote debugging session no longer prompts twice to create a mapped URI". (Bug 80125)
• Prefs: Fixed failure to load preference files containing high-bit characters. (Bug 80676)
• SCC: Fixed bzr status failing to detect all files in a folder. (Bug 80431)
• OS X: Workaround for custom menus crashing. Custom menus in projects and toolboxes are no longer available on OS X due to an internal error in the underlying Cocoa UI code. (Bug 80697)

5.0 Beta 1 Bug Fixes

• CSS: Removed autocompletion fillup characters that got in the way of regular usage. (Bug 80063, 80126)
• Debugger: Fixed space key failing to toggle breakpoint state in breakpoints tab. (Bug 80163
• Multi-window: Added support for breakpoint handling when multiple windows are open. (Bug 79117)
• Fixed error indicated by console error messages referencing "ko.dbg.manager". (Bug 80279)
• Added background syntax checking support for Python 3.
• Tabstops in snippets and templates are now implemented with invisible markers in the buffer. Komodo now uses highlighting/outlining instead of chevrons to delimit them. Nested tabstops are now possible. (Bug 80201)

5.0 Alpha 3 Bug Fixes

• Remote debugging fixed (dbgp URIs not working in Alphas 1 and 2). (Bug 80017)
• Vi Emulation: Fixed the 'r' command (replace character). Now correctly maintains the same cursor position. (Bug 79021)
• PHP: Fixed autocompletion when an instance name is the same as the class name. (Bug 70015)
• SCC: SCC operations on project folders working again. (Bug 79687)
• Komodo now saves the layout information of multiple windows on shutdown and restores them on restart. (Bug 79920)
• Windows: Fixed problems with sub-process launching (affecting debugging, background syntax checking, run commands, etc.) when starting Komodo from the command line. (Bug 76208)
• OS X: HTTP Proxy dialog is now a real dialog window, not a sheet. (Bug 74504)
• Fixed large memory leak in Find/Replace. (Bug 78638)
• Snippets:
  • Extra newline no longer added at insertion point. (Bug 78354)
  • Snippets now use spaces instead of tabs. To insert an actual tab in a snippet you'll need to paste one in. (Bug 79809)
  • Indentation fixed for snippets containing selections. (Bug 72662)
• Fixed JavaScript debugging for Firefox 3. Connection was failing due to attempt to use obsolete Firefox 2 code. (Bug 78845)
• Macros: The syntax checker no longer complains about return statements in the top level of macros. (Bug 78810)
• Perl: The interactive shell now displays overloaded objects, and also displays regexp objects. (Bug 79784)
• PHP: Obtain the correct expression for static class variables. (Bug 79991)

5.0 Alpha 2 Bug Fixes

• Windows: Fixed crash on startup caused by checking a trial license. (Bug 79607)
• Restored missing application icon for Komodo Edit. (Bug 79539)
• Fixed 'Refresh Status' not causing a status update on remote files. (Bug 79567)
• Mapped URIs: Komodo no longer adds an extraneous slash after protocol names. (Bug 78847)
• Sections List: Fixed section types for languages using section_regexes. (Bug 79073)
• Fixed print preview. (Bug 79701)
• Continuing work on sidebar and tabs UI.
• Miscellaneous plugin fixes.

5.0 Alpha 1 Bug Fixes

• SCC:
  • SVN was slow to update modified status for paths that contained spaces. (Bug 79065)
  • Enabled the diff command when a file has a conflict. (Bug 78883)
  • Added "Don't display this dialog again" option to File|Revert dialog box. (Bug 78328)
• Tcl Interactive shell menu option was grayed out - not respecting Tcl preferences. (Bug 79111)
• Active project state correctly saved between Komodo sessions. Previously, the last project opened at session start would be the active one. (Bug 78285)
• Unit Testing: Fixed TAP parser problem (Perl) causing failed tests to appear as passed. (Bug 78781)
• Keybindings: SCC commands can now be set in preferences. (Bug 78938)
• Windows Powershell language support. (Bug 78905)
• PHP: Code browser now shows functions inside alternative syntax conditionals. (Bug 78957)
• PHP: Fixed code intelligence not working with chained function calls that contained function arguments. (Bug 77834)
• Remote Files: Invalid HOME environment variable would break the remote file dialog. (Bug 72402)
• Fixed bug causing autocomplete to only display on primary monitor. (Bug 38281)

Known Issues

To view the status of outstanding Komodo issues, including those that have been fixed in this release, or to add comments or additional issues, please visit the Komodo Bug Database.

Installation & Upgrade

• Windows Vista will prompt you to either 'Allow' or 'Deny' the installation. Click on 'Allow' and Komodo will install normally.
• The Komodo installer requires up to 230 MB in your TMP directory (as indicated by the value of your 'TMP' environment variable) during installation, even if you plan to install Komodo to another drive. If you do not have the required space on this drive, manually set the 'TMP' environment variable to another directory with sufficient space. Ensure that you have enough space, temporarily, for installation. (Bug 7057)
• If you try to install Komodo on Windows and the MSI install fails with error 2355, your MSI file is corrupt. Please download Komodo again and re-run the MSI install. (Bug 7405)

Startup

• The first time Komodo is run after installation, it must register a number of components with the operating system. This causes the first launch to be considerably slower than subsequent launches.

Editing

• Tabstop syntax has changed in Komodo 5.0. Abbreviation from the Toolbox|Samples directory of pre-5.0 versions of Komodo will not work as expected with the current implementation. Delete the older versions to use the ones featured in the "Samples (5.0.0)" directory. Alternatively, if you have made modifications to these snippets or have implemented your own using tabstops linked by name, consult the documentation and revise them using numbered linking.
• By design, Komodo does not attempt Replace in Files operations on unknown file types. However, file association preferences can be used to associate a user-defined extension with a language category (e.g. "Text") which then enables replacements for that file type.
• Linux users may need to install the SCIM platform packages for non-ASCII text entry. See "Linux Software Prerequisites" in the Installation Guide for details. (Bug 70812)
• Autocompletion on the following Python Win32 modules is not yet available: dbc, perfmon, pywintypes, win2kras, dde, pythoncom, and the binary sub-modules of win32com.
• The macro recorder will record events that it cannot handle, such as the opening of dialogs. The only dialog that can be opened via a macro is the Find dialog; other dialogs will cause the macro to stop.
• Languages that are read right to left and Asian languages are not supported. All Latin and Cyrillic languages are fully supported. (Bug 29702)
• On slow networks, users may notice performance degradation when editing files on network machines. Performance can be improved by disabling the Komodo function that checks if files on disk have changed. Use the Editor Preferences to disable this feature. (Bug 18297)
• Interpolation shortcuts in snippets are not executed when the snippet is inserted in the Editor Pane via dragging and dropping.
• On Linux, GTK2 hard codes 'Ctrl'+'Shift' to use international input. Therefore, all key bindings involving 'Ctrl'+'Shift'+ (any valid hexadecimal character) do not work in Komodo. A workaround is to start Komodo with the command: export GTK_IM_MODULE=xim; ./komodo'. Otherwise, key bindings of this kind must be changed. (Bug 38205)
• When copying text that does not have Windows line endings into another application, which expects Windows line endings, the text may not retain the desired formatting. The text is often pasted as a single line. (Bug 36791)
• Code snippets that are 8-bit-encoded and contain high-bit characters may have the wrong encoding (or no encoding) when inserted from the Toolbox into a UTF-8 encoded file in the Editor Pane. (Bug 36769)
• When editing a code comment in Komodo you may use <Shift+Enter> to start a new line within the comment -- the comment prefix is added automatically. Komodo may fail to properly add the comment prefix if many new lines are added quickly with repeated <Shift+Enter> presses. (Bug 38658)

Debugging

• PHP: A non-empty doc_root setting in php.ini causes a 'No input file specified' error when starting a local debugging session with CGI emulation. The Web Developer Suite 2.0 package and others use this setting, and it is copied into the debugging version of php.ini during PHP auto-config. Comment this setting out in the file specified in 'Preferences|Languages|PHP|Path to alternate PHP configuration file' to avoid this problem.
• Python: Breakpoints will not work with the Psyco extension enabled. The Komodo FAQ has a work-around solution.
• Tcl 8.5: Tcl Beta releases contain only version-specific executables (e.g. tclsh85.exe and wish85.exe). Komodo does not automatically find these in the path. To use them, specify the executables manually in Edit|Preferences...|Languages|Tcl|Interpreters, or create non-versioned symlinks/shortcuts to the versioned executables.
• The Perl debugger uses alarm() internally. This can conflict with some Perl frameworks and modules (such as POE) which use alarm() as well. To work around this problem, add alarm=0 to the PERLDB_OPTS environment variable (in the Environment tab of the Debugger Options) which stops the debugger from using alarm(). With this work-around in place, the Break Now button and menu item will not work in debugging sessions.
• Using the JavaScript debugger on files with mapped URIs can yield confusing results. Komodo will open the mapped source file rather than querying Firefox for the runtime JavaScript.
• Python debugging with IronPython does not currently work as there is no support for Python debugging hooks in IronPython.
• In PerlApp executables, it is now possible to step into loaded modules, but not to set breakpoints in them.
• The Komodo JavaScript Debugger is incompatible with the FireBug Firefox extension. FireBug must be manually disabled (Tools|Firebug|Disable Firebug) for the JavaScript debugger to work. (Bug 47208)
• PHP 5.0.0, 5.0.1 and 5.0.2 do not work with the debugger extension. Use PHP versions 4.3.10 or greater, or 5.0.3 or greater, including 5.1.
• If the debug listener (Debug|Listen for Debugger Connections) is off, multithreaded applications may not run or debug as expected. Only the main thread operates through the debugger. To debug multithreaded applications, turn on debug listening prior to debugging. (Debug listening is turned on by default.) (Bug 32776)
• PHP configurations that use Zend Extensions (such as PHP Accelerator) are not compatible with the Komodo PHP debugger. (Bug 21890)
• Due to the way the core Perl interpreter works, it is not possible to step over "require" statements. (Bug 18776)
• You cannot debug 'freestanding' executables created with the PDK in Komodo. Instead, build a 'dependant' executable, which requires a local install of ActivePerl.
• The variable watcher does not work when debugging \\machine\d$\path\to\perl_script.pl. It does work when opening the same file via a UNC path that does not include a '$' character. (Bug 19558)
• When debugging remote applications, Komodo fails if the remote process does not have valid stdout and stderr handles. GUI applications, such as those started with "wperl.exe" or "pythonw.exe", or those using the Pythonwin or wxPython frameworks, or those with certain embedded applications, can have invalid stdout and stderr handles. Until we resolve this issue, try to run and debug your remote program under perl.exe or python.exe.
• Python, XSLT and PHP debugging require TCP/IP to be installed and properly configured, even if you are debugging scripts locally. While TCP/IP is configured by default on most systems, early versions of Windows may require manual TCP/IP configuration.
• When debugging a GUI script in Komodo, adding a "watched variable" when not stopped at a breakpoint can cause Komodo to hang. You must manually terminate the script being debugged to stop Komodo from hanging. The problem occurs because the GUI script, while in its message loop, does not respond to Komodo's request for the variable value. (Bug 23516)
• If the Komodo debugger is configured to use a specific port, when Komodo is shut down, the port is sometimes not immediately released. If Komodo is restarted before the port is released by the operating system, a message is displayed advising that the system is unable to bind that port. As a workaround, we suggest configuring port 0 as the Komodo debugging port and using the debugger proxy for remote debugging. (Bug 32821)
• Breaking into a running Perl script can only occur while crossing sub boundaries in the Perl code, as that's currently the only chance the Perl debugger has to check to see if the IDE has sent the break command. (Bug 35611)
• When debugging Perl, if you set a breakpoint on the while statement, the debugger stops on the breakpoint only once, namely before the first pass through the loop. This is a limitation in the Perl interpreter. (Bug 34866)
• Komodo debugger uses TCP/IP networking for communications. On systems with firewalls installed, the debugger may fail if the firewall is not configured to allow Komodo to listen for connections. On Windows, you may see a "Windows Security Alert" dialog asking if you want to allow Komodo to listen for connections, you will need to unblock Komodo. (Bug 21684)
• The Perl debugger cannot trap fatal runtime errors. Users can accomplish this in their code by wrapping problematic code in an eval block, and then testing for an exception. (Bug 33855)
• Komodo does not provide proper source debugging in Python exec and eval statements. This is a limitation of Python's interpreter. (Bug 40336)
• When debugging PHP on a remote Linux machine from a local Windows machine, the debugging option "Try to find files on the local system when remote debugging" has no effect. This is due to differences in Unix and Win32 file paths. (Bug 39137)
• When debugging Python, Komodo does not permit you to set local variables in the interactive shell. However, you can edit those values from the program's variable viewers, such as the Watch and Locals panes on the Debug tab. (Bug 36794)
• When debugging PHP scripts on Komodo with CGI emulation, you may need to change the setting for cgi.force_redirect in the php.ini file. You may also need to set an environment variable in the Debugger Options dialog box: "REDIRECT_STATUS=200 OK". These settings vary depending on your system and the configuration of PHP. (Bug 35021)
• When Debugging PHP, the HTML pane of the Output tab does not refresh automatically. To refresh the contents of this pane, click the "Reload HTML view" button on the Output tab. (Bug 36999)
• Komodo supports full Unicode debugging with Perl 5.8. Although Perl 5.6 can be used for debugging programs with single-byte encodings (e.g. cp1251), it is recommended that programmers with multi-byte character sets upgrade to Perl 5.8.5 or better. (Bug 36760)
• When debugging Python, if you launch the debugger from a directory containing a module with the same name as one of the modules used by the debugger, the wrong file is used. For example, if you have a file named logging.py in the directory where the debugger is launched, the debugger will fail. (Bug 36783)
• When stepping through Perl files, the Komodo debugger displays the wrong print results in the Locals window of the Debug tab. This is because Perl provides only one iterator for each collection variable. The Komodo debugger must iterate through a hash or an array in order to display the values in Komodo. A workaround is to display the Watch pane instead of the Locals pane, and type the names of the expressions that you want to view. (Bug 33668)

Interactive Shell

• The interactive shell does not initialize properly when invoked while the Command Output tab has focus. To avoid this, switch focus to another tab or sidebar before starting the interactive shell.
• Perl: Only pattern variables $1 .. $9 are preserved across each query. (Bug 34528)
• Python: The getpass package requires the use of a tty on UNIX systems. Komodo does not provide a tty in it's interactive shell so getpass will fail with an exception. (Bug 34259)

Source Code Control

• The SCC Checkout wizard does not correctly handle password authentication. SCC checkouts requiring password authentication should be done at the command line.
• A bug in CVS will cause WinCVS and TortoiseCVS to detect file changes when a Komodo project has merely been opened. The problem is likely a bug in the cvshome.org executable or in the cvsnt.org executable, which are used by both WinCVS and TortoiseCVS. (Bug 21085)
• Komodo's integration with the Perforce commit/submit command cannot commit files that are not in the default changelist. These files must be submitted via an external interface (e.g. p4, P4Win). Note that any files checked out inside Komodo are in the default changelist, so this limitation should only apply to users who already use an external interface to their Perforce repository. (Bug 27070)
• If the Perforce connection cannot be established, checking the status of files in a Perforce repository will hang Komodo. (Bug 35058)
• If you are using CVS Source Code Control, note that the very first time you log in to a repository, cvs.exe fails to create the .cvspass file correctly and will return an error. Repeat the command to login a second time and correctly generate the file. This is a CVS bug. (Bug 20353)

Mac OS X

• If you have two drives with the same name, and you use the file open dialog in a Mozilla application, the directory menu (top middle of dialog) may crash when clicked. To avoid this, rename one of the hard drives.
• New Custom Menus created in a Project or in the Toolbox will not appear until Komodo has been restarted.
• Throughout the Komodo documentation there are references to key bindings that use the 'Meta' key. This key may be better known to OS X users as the 'Command' key. (Bug 41959)
• Komodo will shut down and restart itself the first time it is run after installation. (Bug 40143)
• Display of text during editing ("painting") may sometimes be slow or pause momentarily.
• Certain UI elements stop working after changing key bindings. Restarting Komodo fixes this. (Bug 38683)
• When saving a file, Komodo does not set file information (type and creator) for the OS X Finder to know that Komodo created the file. (Bug 38745)
• Breakpoints cannot be removed when debugging XSLT scripts. (Bug 40072)
• PHP debugging will not work with the PHP build distributed with OS X because it does not load external modules. To use PHP debugging on OS X, build PHP from source or download a binary from http://www.entropy.ch/software/macosx/php
  (Bug 39901)
• Komodo is sometimes recognized as a web browser by some applications on OS X (e.g. Safari's "Default Web Browser" setting). Using Komodo as the default web browser is not recommended.
• Application menu items that have multi-key key bindings will not show their key bindings in a pop-up tool tip on OS X. This is a limitation in OS X.
• Context menus may not display unless you hold down the mouse button for a period of time. This is because the Komodo editor is implemented in Mozilla as a plugin, and it does not access the appropriate context menu event to handle this behavior properly without interfering with other mouse events (for example, drag and drop). (Bug 41216)
• Due to a limitation in the Mozilla code base, key bindings for the Next File and Previous File options on the Window menu are not displayed next to the menu items. The key bindings are 'Meta'+'PageDown' to view the next file and 'Meta'+'PageUp' to view the previous file. (Bug 40716)

Linux

• The Fonts and Colors pane in the Preferences dialog box displays the same list of fonts in both the Fixed and Proportional lists. There is no programmatic way to identify whether a font is proportional or not on GTK; therefore, users must know the properties of the individual fonts when modifying these values. (Bug 27206)
• Install Komodo into a directory path that only includes alphanumeric characters. Komodo is known to have trouble with paths that include spaces and some non-alphanumeric characters.
• Key bindings defined in the window manager (such as KDE) take precedence over Komodo key bindings. In the case of conflicts, you must either change the Komodo key bindings or the window manager key bindings. (Bug 30926)
• You cannot move an existing Komodo installation to a new directory. You must uninstall Komodo from the existing location and reinstall it in the new location. (Bug 19478)
• When using the PHP Configuration Wizard, you must have write access to any directories you specify in the wizard. (Bug 37176)
• Red Hat Linux 9.0 is known to have threading library bugs in its glibc that may cause Komodo to hang in certain situations. The recommended solution is to upgrade to the latest glibc for Red Hat Linux 9.0. (Bug 24340)
• Using colon-separated include paths in the Perl shebang line causes a parse failure on some versions of Perl. Instead of using "/usr/bin/perl -cwT -I/path1:/path2 yourscript.pl", try using multiple include arguments such as "/usr/bin/perl -cwT -I/path1 -I/path2 yourscript.pl"
  (Bug 33524)
• Komodo may not start up correctly on some Linux systems if C++ compatibility libraries have not been installed. On Fedora and Red Hat systems, install the "compat-libstdc++" package. On SuSE, install the "compat" package. On Gentoo, as root, run emerge lib-compat. This is not thought to be a problem on Debian systems. (Bug 36244)

Other

• A limitation in the parser used by the DOM Viewer causes HTML elements embedded in JavaScript strings to appear as element nodes of the current document. Placing the JavaScript in a CDATA section or a comment avoids this problem.
• Komodo inherits a Mozilla bug whereby certain video drivers on Windows cause Komodo to crash. If you experience this behavior, upgrade your video driver to the latest version. If the problem persists, reduce the color definition assigned to the driver (Control Panel|Display|Settings). (Bug 32746)
• Komodo inherits a Mozilla bug regarding display on dual-monitor systems where the secondary monitor is to the left of the primary monitor (causing negative coordinate results). The Komodo display occasionally fails to refresh; Komodo must be stopped and restarted to fix the display (Bug 26852)
• When using Komodo's Preview in Browser feature, users running Mozilla on Windows XP Pro, Windows 2000 Pro and Windows 98 may find that they cannot exit Komodo if Mozilla is still open. If this should occur, close all open browser windows before exiting Komodo. (Bug 26431)
• The Palm Desktop for Windows software makes exclusive use of the 'Ctrl'+'Shift'+'T' key combination, thus making this combination unavailable in Komodo. (Bug 27851)
• When using the PDK Build Standalone Application feature in Komodo with Perl 5.8.0 on a Linux installation where the environment is set to use UTF-8, you must add a module 'utf8' on the modules tab. This is the equivalent of 'perlapp --add utf8'. This does not affect Perl 5.6.x or future versions of Perl 5.8.1 or higher. (Bug 26898)
• On Windows NT, some interactive commands may not work properly when run from the Command Output tab of the Output Pane. You must run these commands in a separate shell. (Bug 23176)
• Perforce client version 2001.1 and previous for Windows is known to hang when used for Komodo's Perforce integration. Upgrading to the most recent version of Perforce is known to fix the problem. (Bug 19959)
• The Output tab cuts off lines at 250 characters. (Bug 20711)

Lines in files that have different line endings are not displayed differently in the diff (unless other differences are present), but a warning is provided to the user in the 'diff' window, or the 'no difference' dialog. (Bug 32932)

• If you rename a folder that was added to a custom menu, the name is changed in Komodo's Toolbox but not on the menu itself. A workaround is to move the renamed folder out and then back into the associated custom menu icon in the Toolbox. (Bug 36679)
• A newly created custom menu is added to the Toolbox but is not immediately displayed alongside existing toolbars. Restarting Komodo causes the new toolbar to display. (Bug 40078)
