I see many posts about the trackball not selecting, only moving one direction, etc. My problem is the trackball selects as soon as I move it. It might scroll through one or two messages but then it selects without being pressed. Same thing in phone menu, etc. Is this a symptom of a dirty trackball? Thanks.

You may also have a bad trackball.
They are inexpensive and easy to replace.
