I had a similar problem with a mouse on a IIcx.  No problem, it was under
warrantee, so I took it in and had the mouse replaced.   The new mouse
was of a slightly different (older, I think) design from dealer stock.   It
too began exhibiting symptoms of "jumpiness".   Cleaning helps only for a 
few minutes, in fact, merely removing the ball and replacing it seems to help
for a few minutes.   I finally solved the problem by buying a "Little Mouse"
(optical jobbie) from a mail-order place.  That mouse has only been around
for a month or so, but so far no problems.

However, I've seen this mentioned on the net before, about three months ago.
There were a half-dozen or so complaints of the same problem, all with
cx's I believe (though this was before the ci price cuts).   I can't help
thinking maybe there's a real problem out there hiding somewhere in Apple's
mice, system software, or ADB hardware.   How many others are having this
problem?
