I have found that quite a lot of the keys on my keyboard are mapped wrong for example the up arrow inputs Key print screen, the left arrow inputs Key right alt and both right and down arrows are Key unknown key. The enter key on the number pad turns out to be Key down.

Is there a way to fix this as the only thing I found for configuring keyboards was for the layout which doesn't affect this.

I'm running DosBox 0.72 on Ubuntu 9.04 64bit with a standard full sized uk keyboard.
