Scroll wheel won't work on Logitech Trackmen Wheel-10.6

[markw10]

I have 2 MBP's, a Mac Pro, and a Mac Mini. On all of these I use a Logitech Trackman Wheel with. I updated the first 3 machines to Snow Leopard and the Logitech Trackman Wheel continued to work fine.
I then upgraded the last MBP to Snow Leopard. For some reason the scroll wheel no longer works on the Logitech Trackman Wheel. I am able to use the ball to move around the screen, the buttons still work, but the scroll wheel won't work. Any idea why this would happen? Thank you for your help.

Logitech drivers or OSX's built-in drivers?

Are you using Logitech supplied drivers or just OSX's built-in drivers?

I also have a Trackman Wheel and no problems using OSX's built-in drivers.

I don't know how I fixed it exactly but I did a couple reboots, once without the trackball plugged in and now it works fine. Unfortunately I don't know what fixed it though.
