There seems to be something wrong with general Linux mouse behavior.
Even on ordinary optical mice (like the HP I'm using now), the mouse
works fine about 98% of the time; then it jumps to the top of the
screen inappropriately.  (Running Ubuntu Jaunty with 2.6.28-11-server

I'd noticed this with touchpads and assumed it was a buggy touchpad,
but it seems to be a more generic bug somewhere in Linux.

The latest Ubuntu (karmic beta) disables tap-to-click by default,
which is a regression (see
with it's more-than-a-dozen duplicates and see also #441013).  It
turned out that there was a lot of complicated interaction behind the
scenes that would make it work, fail, work, fail, ... with different
versions of various packages.
