CADmouse jittering

[drkieffer]

We just installed new CADmouse devices in our design office. On one workstation, the mouse cursor moves, or jitters when the mouse is not touched. On my workstation, it is rock steady. The only difference we can see, is mine has firmware v1.03, and the jitter mouse has firmware v1.04

Any thoughts on this? you really notice it when not touching the mouse, but it IS doing this when moving and trying to select things too.

Thanks,
Dae

Solved.

A second mouse was plugged into the workstation, and sitting on top of a cd/dvd.
