    I love the mouse (is it the mighty mouse?) which comes with the imac. The little scroll ball is brilliant especially for say scrolling down in itunes . BUT I always find that sometimes it won't work in a variety of different ways.


    1) Sometimes it will let me scroll down but not up
    2) sometimes up but not down
    3) sometimes not up or down
    4) occasionally it works both up and down.

    As I type this I can go down but not down-ahhhhh.

    Iv'e had this problem on both our older imac and now our new one. It can't be dust and muck and the ball does rotate.

    Why can't the ball just work all the time.

    Any tips??

    It gets dirty. Turn it upside down and rub it on a piece of paper. It will eventually become uncleanable.

    Yea dirt gets in it...you can also try some isopropyl alcohol on a cloth and rub it (just make sure you don't get any in the mouse).

    SLIGHTLY dampen a clean, lint free cloth. Hold it in your hand. Turn your mouse upside down and vigorously rub the track ball against the cloth.

    Do this every once in a while, before problems start.

    Oh, and try to have clean fingers when you're using the mouse. My wife mucks my mouse up if she's been eating potato chips before she's on the computer. Grrr......
