Has anyone else notice this. Maybe its just me. I felt like i didn't hear this before. Other the clicking sounds, it sounds like the trackball is rubbing. I have had the Pearl since day one and under normal use. I tried cleaning the trackball thinking that might be it. It just sounds like its rubbing against something inside. I am not sure.

I've had three and all did that. Even with click turned off...

might be some kind of dirt..

Could be some dirt under the ball. Other then taking it apart, not sure what else todo. It's kind of annoying now that I know its there.

It actually might of been a dirty trackball. I took a suggestion from a recent post on using a alcohol cleaning cloth. Seems better.
