Yes, I have fixed it for my current keyboard, and it's just 3 keys.  It's 
an asteroids clone.  How complex could the controls get?  Is there any 
pattern to this "some keyboards can't detect multiple keypresses" stuff?  I 
want to make sure people can play the game, becuase as it is now, you 
cannot change the controls without altering the source.
