X and Fluxbox :: Problem with keys

Greetings all

Been a while since my last post here, but now this small problem is starting to annoy me so I thought I would consult you all for help again ;)

I've installed DSL on a HD in and old dog. And the system is working very fine. Very indeed.
There's only *1* problem with it though, but it's annoying.
The system is setup to be a ThinClient like computer and the primary task is to fire rDesktop. That works and all is happy. BUT the problem is that once the user tries to use the numlock keys something is going wrong somehow. You see.. he might be typing "1000" in an Excel document in the rDesktop screen and all it will display in the coloum is "1" until he presses another NON-numlock key.. then it'll display "000" plus the pressed button.  

If he is using the standard 1-0 numberkeys at the top of the keyboard all is working just great.

Can I remap the numlock keys to send the same signal as the numberkeys on the top of the keyboard ? If yes.. then how ?
Anybody else has this problem.

This is a quite serious problem since this computer is running as a test computer in a local government here in Denmark so it really has to be fixed... I've already exceeded the time where i should have fixed this.
