A kind gamer pointed out a major bug in Bobby version 1.6 (and possibly prior versions) on Windows. While playing the game in fullscreen mode, when you quit the game, your Windows taskbar will be missing. To get it back, you have to run the game again and switch to windowed mode, then quit with windowed mode active.
This patch fixes the issue in the full version. It should work whether you got the game from this site, or any of our distributors. Just point the patch program at the directory with Bobby.exe in it. A new Lite/Demo version will be on this site momentarily as well.
Apologies for the problem!
