Hi Tom,

I had forgotten I posted this. As an interum measure we replaced the
trackball with a mouse. Now:

1) The trackball had been connected directly to the USB connector(s) on the
back of the computer. We also tried using the USB header with an appropriate
cable. Neither worked properly (trackball *might* work for a very short time
and then quit).

2) Yes, we've since moved the trackball to an ECS VIA KT600-A (VIA KT600
chipset) and it is working perfectly. Both systems are running Win2K.

3) We purchased a new trackball and it is working perfectly on the AN35
Ultra - go figure

Hopefully the USB situation was just a slight glitch between that particular
trackball and the AN35.

Thanks for the reply.
