Search for a utility called "ADB Reset." Whenever any ADB pointing device flakes out (mostly KVM issues in my case) I run it, the cursor disappears for a sec or two, and pops back up running just fine.
Rip out that pestiferous TorquemadaPad and put in a spherically correct TrackBall, far more useful for graphics and much more elegant in design and use. No mfr. switched to TouchPads from TrackBalls because they were better, they did it because they used less room, had no moving parts, excepting the buttons and cost less to make and support.
The first touchpads really sucked and while current ones seem more natural to folks, most of them have never seen nor heard of a TrackBall, much less a tailed rodent with a ball inside!
The tactile feedback of the spherically correct pointing device is king! :approve:
