You said you now have Windows 7, but you didn't say whether it was a new computer or just an upgraded OS. It wouldn't make sense for a problem like that to transcend different machines. Are you using the same mouse or a different mouse? Have you tried a different mouse? Double check the snap-to settings also, because that is a setting that moves the mouse after you click.

Is your mouse wireless or wired? I have a Logitech that has a little USB transmitter. I did find that it had problems when it was plugged into the USB port right next to the eSATA port. I moved it to a different USB port and it worked fine.

Just a few things to think about.
