Unofficial Fix for Windows 7 and Windows Vista
A workaround for this Windows 7 and Vista palette error is killing the explorer.exe process, then starting the game.
However, there are more compatibility issues. On some machines, the game crashes with a "Worms World Party has stopped working" error message. There is no known fix for this problem.
