Hello, Am I correct in saying that you are plugging in the mouse, it acts in the strange manner that you described, you unplug it, plug it back in and all is fine? I have no idea as to why this would happen, but, out of curiosity, are you plugging in the mouse while the machine (or at least X) is on? Leonid Grinberg lgrinberg@gmail.com http://www.lgrinberg.org
