Thomas,

Thank-you very very much!!! This is an excellent solution and works like a 
treat!! Thanks so much.

JS.

>OK.  You asked for it.  Below is a short C program which will check the 
>state of the NumLock key and synthesize a keydown/keyup sequence of the 
>NumLock key if it's down.  Works on my box, which is Win2K, but I'm led to 
>believe from the documentation that it should work with any 32-bit 
>implementation of windows.

>"numlockoff.c") then run gcc on it (e.g. "gcc -o numlockoff numlockoff.c"). 
>  Then add that to a convenient location on your client systems and add a 
>call to it in your X startup script.
