That is pretty odd.
Have you tried reinstalling your mouse drivers or tried using a different mouse and/or keyboard?

Ah... I was going to ask if it was a notebook. What does it have for built-in pointing devices; is it touchpad-only, or a touchpad/trackpoint combo?

Yup- that's pretty much where I was headed.
I did have a client a while ago who had something similar happening- it turned out that she was occasionally resting her palm on her touchpad's (overly-sensitive) scroll/slider button while she was typing... :cheesy:

You can definitely have all three of those devices enabled at the same time, but because all functions of each pointer are simultaneously active, something like a faulty/sticky/overly-sensitive function key associated with the trackpoint or touchpad could cause the behaviour you're experiencing even though you might be using the mouse as your primary pointing device.
On the IBMs you should be able to use the IBM-supplied laptop configuration utility to disable the trackpoint and/or touchpad; try disabling those one at a time to see if you can determine if one of them is the root of the problem.
Looks like we were posting at the same time... Let us know what you find out from selectively disabling things.
