My keypad doesn't work


I can't get my keypad to work under X.1. I have a swedish full-size apple keyboard that came with my G4 AGP, and I have tried the us & swedish options in "keyboard menu" but the numeric keys on the keypad won't work. I thought it maybe had something to do with num lock but it's the same problem with num lock active and inactive. It's only the numeric keys, the +, -, *, /, ans so on, works just fine.

Have anyone got an idea of what could be wrong?

OS X rocks, but aqua theme is still to slow :(
