Several Bugs of unknown origin (DirectX ? DXC ?) are known:

1. Loss of background buffer - resulting in a black and white altering screen.
	Possible solution: Installation of a newer DirectX Version.
			   Restarting the game.

2. Conflict with 'strange' graphic modes (e.g. 1152x864) results in bluescreen.
	Possible solution: Change graphic mode to 1024x768x16

3. Music tempo much too high
	Possible solution: Start game again
