A friend of mine is having a problem with internet exploerer. Well, i'm assuming that it's IE. The problem is, whenever he opens IE and trys to type something in the address bar, the mouse will start to shake really fast, kind of just like vibrate back and forth, and wont let him do anything. Now i've seen it happen and the only time it happens is when you ope IE. You can open any program on his computer and it doesnt do it, only on IE. Anyone have any idea what would cause this?
