I have the ipac- ps2 and optipac -serial combo..
I have a question regarding the optipac though...
It seems that the mouse operation in windows seems to act strangely. I have tried with both win98se and xpsp2 with the same results to give you an idea.
It seems that the mouse only works in the up and down direction. If I remove the ipac programming software and reboot the machine it goes back to standard operation and works fine in all directions.
Also, some times after reboot the trackball will only slightly work with numerous "spins" able to only go about a quarter of an inch on the screen in any direction, and the cursor shakes back and forth.
I have the opti drawing power from the ipac, and that is a ps2 connection.
any help appreciated
