Have you checked the hardware? (connections tight, no sticky encoder
wheels, no open wires, etc.) You could test the Mac with someone
else's mouse if you can borrow one.

Even if all that's OK, it could still be a hardware problem (i.e.,
encoder counter or something like that) inside the Mac. Not having
access to any Mac hardware manuals (doubtless any that exist would be
published without Apple's permission), I can't tell you specifically
where to look. My guess is it's going to be either one of the custom
chips or a PAL (with the READ fuse thoughtfully blown by Apple, of
course :-( .

If the problem persists, try your software on another Mac. It's really
unlikely to be a software problem if it's specific to one machine
(although in the case of the fellow who removed his batteries to
initialize default settings, it seems it can happen.)
