Mouse won't scroll

[John Aldrich]

Ok... I just upgraded to F15 last night and now my mouse scroll doesn't 
work. Any ideas? I've got a "Logitech Cordless Optical Mouse". The buttons 
work fine, it's just the scroll doesn't work. :-(

I've gone into Systemsettings and it looks fine there... seems similar to 
the problem that used to be fixed by going in and hacking the X86config file. 
'Course we don't use that any more, so I don't know how to fix this.

I have already tried CTL+ALT+Backspace thinking it might be something 
there... should I reboot entirely???
