Those who experience force closes please try to reproduce the problem and look into the logcat. You can find such tools on the Play Store:

I have absolutely no idea why modifying any Mouse setting would end up in force close, since they're pure API based Preferences.
Any tuto ? How to do a catlog ? Don't know exactly if I should send you the entire logcat ... ?
