I have a problem with my mouse, sometimes the cursor instantly moves to the top or to the bottom of the screen. It's a couple (3 or 4 I think) of weeks since this started to occur, but it have gotten worse. At start it happened once a day maybe and I didn't care what it was. This normally happens about every tenth minute, but sometimes it can take hours for it to happen and in other cases it can happen 10 times in a minute. It normally happens when I do something, I'm not sure what, but for instance it often happens when I click a button. I haven't seen it happen while the mouse wasn't moving. Sometimes after having moved the cursor it keeps sending either left or right clicks until I click that button, but that only happens once in a while. I have noticed it happens more often when I play CS:S, most likely because of the mouse movement and the clicking. The reciever is standing where it has for the last 8 months, right next to my screen, about 0.7 m from the mouse (~2,3 ft). Does anyone know what it could be?
