Ah, thanks!!
Maybe this is why some game (I believe it was UT) broke...
Darn, why didn't I discover that when I stumbled on that place years ago?

But don't you think keyboard and joystick might need the same code??
(keyboard has it as well, but with completely different code --> mess)

This could probably be cleaned up.
