Hey Misty

I think I know what the problem is. I use an OLD OLD Kensington trackball. When I don't have the right driver the cursor jerks around just like this. Kensington doesn't even supply the driver for mine anymore: I moved to a new PC at work and had to use the "DO NOT USE WITH YOUR DEVICE EVER EVER EVER NOT SUPPORTED DANGER!!!" driver.

It works fine, but since this really isn't the right driver for my device that may be the problem. My co-workers all say that the scrollbox doesn't affect their cursor at all.

I'm getting a new Logitec trackball sometime in the next few days; I'll post and let you know if that changes anything.
