This confirms my suspicion. I had to replace a IIcx mouse recently,
too. At first I thought all my inits and other gadgets were
interfering with mouse tracking. But after reading about other people
having the same symptoms, I exchanged the mouse for a new one, and the
jumpiness was gone. The only major problem was to find a dealer who
had mice in stock...

I suggest that everyone who has this problem take his mouse in for
replacement immediately if it is still under warranty (mine was
already 11 months old, thank god, Apple got reasonable about
warranties a year ago!). Judging from the number of people experincing
juminess, I predict a major mouse shortage in the near future.

Futhermore, we all should complain to Apple at their new customer
(dis)satisfaction number about the cheap new mice. They may wake up
and realize that one old, heavy mouse is cheaper than two or three new
ones.
