Tray icon - uncheck this to remove QM tray icon. To open QM window when the icon is removed, press Ctrl+Alt+Shift+Q. Or, click QM icon in Start Menu -> Programs -> Quick Macros 2, or in Windows Explorer (that is, run QM when it is already running). Also you can set to show the icon only when a macro is running. Then the icon does not respond to mouse clicks.
Run at startup - run QM when Windows starts. Administrators and power users can change this setting for all users. If set for all users, QM is launched using the registry. If not set for all users, each user can separately change this setting, and QM is launched using the Startup folder.
Check for new QM version - check for new QM version when QM starts. If there is new version, shows it in QM output.
Unicode - if checked, QM interprets text in macros and QM user interface as Unicode UTF-8. If unchecked - as ANSI, like in older QM versions (< 2.3.0) that did not support Unicode. After checking the checkbox and restarting QM, you can click Convert to convert your macros to Unicode UTF-8.
Members: erase category - when you type a category name and select something from the members popup, erase the category name.
Toolbars: always topmost - free toolbars always remain visible. If not checked, a toolbar can be obscured by other topmost window (e.g., taskbar). Regardless of this option, you can make a toolbar visible by triggering it again.
List: expand single folder - when selecting an item or folder in the list of macros, automatically collapse the previously expanded folder. Also, don't show + boxes and lines, expand folder on single click, disable easy label editing. If this checkbox is in indeterminate state, all except collapsing previous folder is the same as in checked state.
List: non-encoded triggers - show short trigger descriptions instead of encoded trigger-strings.
UAC: run as - select what privileges should have QM when running on Vista/7.
Check extensions - check whether QM extensions are working.
Export settings - export QM registry settings to a reg file. Read more.
Debug - some options that can help to debug QM or your macros. Select the 'dump exceptions' options to create crash dump files on every handled and unhandled exception, including QM internal exceptions and exceptions in dlls and other components. Exceptions may be the reason of QM crashes or other weird behavior. You can attach the dmp files to the email when reporting a QM bug/crash/etc. You can delete the Debug folder when not needed. The options are not applied to macros running in other processes.
