Logitech "Marble" Ball works perfectly on both my computer and my wife's. Both using same mouse and Windows XP. We play many PC Games and have not had a mouse problem. Recently downloaded 3 games. No problem with first one but very erratic and jerky mouse on next 2. Happened on both computers. I have most recent drivers for NVIDIA GeForce 8600 GT and using current Logitech drivers. In last instance, mouse seemed to be working ok and then progressively but rapidly got to the point where it was impossable to use. If I go to Windows with game running, mouse is erratic. Shut game down and all is well again.

Any help appreciated. We like the download site and hope we can make them work.
