Default Re: Track ball creating problem in down position

If you are a mechanic, or exposed to grinder dust, roll your trackball up and down by pressing a clean fridge magnet against it. If metallic dust isn't the problem, gently hoover the track ball alternatly running the ball up and down.
My track ball stops working at least once a week because of grinder dust. the magnet trick saves me having to keep dismantling the trackball which is a pain on the 8900
