F11 scroll wheel problems

[Paul Erickson]

I have used a Microsoft trackball explorer 1 for a long time, and now 
with F11 the scroll wheel is acting funny. If, for instance, I am in
Firefox, scrolling down is fine, but if I try to scroll back up, the 
browser skips to the previous page. I have two F11 boxes (32 and 64bit) 
and they both have the same problem. My F6 box, which uses the same 
trackball (kvm between all three) works fine.

I have searched the archives, and google generally, and cannot seem to 
find a solution. I have tried adjusting the mouse sensitivity settings, 
but it has no effect.

Any assistance will be greatly appreciated.
