So I have had this mouse for at least two years and I got extremely mad and slammed it on the desk and immediately I noticed that it wasn't working very well. It did move left to right, but if I tried to move it fast left to right it would glitch out and not move much. It works perfectly when it isn't on the mouse pad but I have been using this mouse and mouse pad for ages, so did I break the sensor on the mouse when I hit it off the desk? I just don't understand why it works on the glossy desk, but not the pad..
