VMware mouse problem

Hello all! I've been trying to setup something at work to showoff
Linux to some people, and additionally I wanted to check out Storm
2k. Since I was unable to appropriate a separate box, I grabbed the
30 day trial of VMware for NT and set it up on my work box, then
installed Storm Linux 2k, and then installed the appropriate tools.

My problem comes in with how my mouse is set up. Mouse is a MS
Intellimouse with middle finger wheel. Symptom is that mouse movements
in X are extrememly erratic, going to the bottom of the screen and
flicking around wildly with slight mouse movements. The setup program
built XF86Config initially tried to use a normal ps/2 mouse for the
protocol and "/dev/gpmdata" for the device. I've tried various
permutations of this and "imwheel", I've tried varying baud rates,
changing the device to point directly at /dev/psaux, etc. I've run out
of ideas. Anyone else see these symptoms and have any ideas? Thanks!
