    Clean the mouse ?

    Or, if cleaning doesn't work, replace it...

    Thanks for your reply and interest in my problem.

    In my OS 9 times it was a somewhat a simple matter to remove the rolling ball and clean it as well as the contact points.

    How do i clean a USB mouse ?

    When i turn the mouse over onto its back there is bright red light and i can't figure out how to or do clean it somehow ?

    Do you use a mouse pad of some kind?
    Even though a mouse pad is usually not needed with an optical mouse, sometimes you will see a difference when you have an erratic mouse.
    Even a plain sheet of white paper can work well as a test.
