Well, I took my new Classic's mouse into work today to see if my jumping 
problem was the mouse or the Mac.  It was indeed the (new, cheaper design)
mouse... the one made in Taiwan.  On direct comparison to the SE's old
heavy mouse, the Classic's was definitely jumpier.

I recall someone coplaining about the Taiwanese mice a few weeks ago, 
just before I got my machine. Anyhow, a colleague and I dug a bit deeper 
into the problem and found what we believe to be the main problem.
The mouse uses a new, smaller ball, which is made of a new black material, as
opposed to the old grey rubber. We also noticed that the old ball is 
significantly heavier than the new one.  In fact the new ball is so light that
it has trouble getting traction on the table... hence it jumps and gets
stuck.

Since there was one handy, we "borrowed" a ball from a Microsoft mouse for 
testing purposes.  It is the smaller size, but of the heavier material. The 
jumpiness went away immediately!  Let's just say it's time for another trip 
to the dealer.

Thanks to the net for making me even notice the problem!
