I am using the Keyboard Mapper to change the following keys:

Q <- [7] (mod2), W <- [8] (mod2), E <- [9] (mod2)
A <- [4] (mod2), S <- [0], D <- [6] (mod2)
Z <- [1] (mod2), X <- [2] (mod2), C <- [3] (mod2)

I <- [7], O <- [8], E <- [9]
K <- [4], S <- [5], D <- [6]
, <- [1], X <- [2], C <- [3]

0 <- no key
cycledown = -, cycleup = +

The reason why I am using mod2 is because I originally wanted to use mod1 (the ctrl mod), however, for some strange reason, it didn't work, so I had to click both ctrl buttons and apply mod1. This caused some commands in the game to not work. So I took away mod1 from ctrl, I changed it to mod2, and applied mod2 to the alt buttons. (So if there's a way to fix this please help.)

The main problem is that when I run Castle Wolfenstein, the game freezes after a while of playing. If there is a way to fix this, can you please help?

Thanks in advanced.
