The following problems are known:

• The second mouse or the joystick will not run properly in the game as second player device.

In this case has the manufacturer of your device an unknown ADB id. If you are interested in getting this to work, you may use the 'ADB-Info' button in the second mouse menu to determine the id of your unhandeled device.
 
• The game is very slow, when a level ends and the picture is scrolled into the next level.

You have now two possibilities: 1.) deactivate the 'scroll levels' option in your effects menu, or 2.) aquire and install a hardware acceleration driver for your special graphics hardware.

You can get more information from your help files.
