[kde-linux] Mouse button/wheel

[brian]

I'm using KDE 4.3 on Kubuntu 64-bit, and have a Microsoft optical 
Intellimouse, one of those with a combined centre button and wheel. 
It's an absolute PITA, because while I'm used to using the mouse wheel 
to scroll, I'm clumsy enough that I unintentionally do a middle click 
at regular intervals, and that has a whole heap of unwanted effects, 
depending on the program in use. In my days of using a certain other 
operating system, I could just set the centre button to do nothing, 
problem solved.

Is there any way to assign a null action to the centre button, and so 
lose at least some of the unintentional input?

Thanks,

Brian.
