On-Screen Keyboard provides a mechanism to launch the application only once, to avoid multiple entry point instances. Such mechanism is based upon mutex objects, although it could happen that the program may end up creating two or more mutexes (a race condition).

- Implement the save/load handler for this feature
- Check the "Use Click Sound" item state accordingly depending if it's enabled or disabled
- Use PlaySoundW() to play the wave sound file from resource
- Add the WAV sound click file. The work is made thanks to Midori Mizuno
In Windows XP, both in On-Screen Keyboard and in Magnify there is a welcome box which is shown upon startup of the application. This feature is already implemented for Magnify in ReactOS which however in On-Screen Keyboard is still unimplemented.
