Multi-question time.

I installed my CP wiring today, and my test run worked out pretty good.
I did find a few peculiarities though.....
If I use my trackball in Windows, the spinner doesn't work (in Windows). If I reboot and use the spinner in Windows (the cursor moves left and right) the trackball doesn't work.
Is this normal..........? (It really doesn't matter as they both work correctly in Mame)
The other issue is with the trackball. When I roll it from left to right, the cursor tends to drift "diagonally up" as well.
Thoughts...?
I did try searching in the forums, but didn't find a thing.
Thanks in advance....
NOTE: I'm using XP, an Opti-pac (USB), an Atari trackball, Oscar Model 3 spinner, and an optical mouse.
