I have Razer Imperator mouse and this started happening recently when playing any full screen video (Windows Media Player, VLC, even YouTube). The pointer randomly appears every couple of seconds as if somebody keeps touching the mouse. I know, it can happen sometimes if you accidentally move the desk or from any other vibration (this mouse is very sensitive), but it happens when everything is still. I've searched all over the web and couldn't find any solutions. It is a minor, but very annoying problem. Can anyone help?
