Greetings. I have an IPac and an OptiPAC with a Happ trackball and a couple supers (there is also a serial mouse in the picture). the Opti is attached via USB and is the only USB device. Everything works fine.
I just added a Vortex to the OptiPAC. The trackball still works fine but the spinner just makes the mouse "jitter" back and forth on the screen, about 2-3 pixels. I get no movement from the spinner except the "jitter" while in Windows XP. The cursor is normal other than the jitter when I move the spinner. I fired up Tempest and get no movement at all with the spinner
The OptiPAC appears to be reacting normally to having a spinner attached (trackball inactive for 5 secs after touching the spinner, buttons still work, etc.).
Thoughts?
