I've got an Ultimarc trackball and for lack of a better way to describe it, it has some "play" or "wobble". A video (with sound) says a thousand words so made this little recording to demonstrate the issue. I have tried cleaning it and adjusting it in the past with no luck. I'm guessing the experts here might have some sage advice for me?
