- TabControl: Tooltip on dropdown list shows full path names now
- New menu item "Lock instance" in Options menu. Only available when "Allow only one instance" is disabled in the settings. "Lock instance" will temporary enable the single instance mode. The locked instance will receive all new launched files
- Some NullPtrExceptions fixed (e.g. in the settings dialog)
Note: The debug build is identical to the release build. But the debug version writes a log file. It also contains line numbers in stack traces. So this may be useful for me when you report bugs.
