I have a problem that only occurs in UT3. I was originally using a Logitech g5, but had some issues with mouse sensitivity changing randomly throughout the map. The mouse was old, and I wasn't exactly happy with it overall, so I went out and bought a Microsoft Sidewinder. Now I love this mouse, however, I get a problem that occurs intermittently, and I am at a loss as to how to fix it. What happens is, my mouse just stops tracking. I can slide the mouse all the way across my supermat (cloth) and my xhair wont so much as twitch. It only does this for a few seconds, but it happens frequently. The mouse works fine in other games and in windows, I am running win xp. Does anyone have any ideas what may cause this or what is causing my issue? PLease help, it drives me crazy,
