Hi. I can no longer use my mouse on my mac desktop computer to scroll up or down. It works just fine if I click on the up and down arrows but simply using the "ball" and scrolling either vertically or horizontally does not do anything any longer.

Is there a fix for this? Is this a common problem? is there a way to "reset" the computer so my mouse functions are restored? I have gone to "system preferences" and clicked on the mouse options but nothing seems to work.

If you are using the Mighty Mouse, then it is a common experience that we all have. Mighty Mouse is extremely flawed in that sense, but I still enjoy the aesthetic aspect of it. My wired Mighty Mouse has been rendered useless after less than a year, while my wireless Mighty Mouse is still going strong despite owning for a much longer time. Anyway, here's what you may want to try.

1) Try turning the mouse upside down and run it on paper a couple of times. Apply pressure but not enough to spoil the internal mechanisms, mind you. Run it horizontally, vertically, in circles, whatever. Just make sure you get a good rolling out of the mouse. It should work after that.

2) Try a cloth this time around, a slightly moist one would be better as well. Try to do the same thing on the cloth as I have mentioned with the paper, and that should work.

3) I have read about running the mouse upside down over wet tissue, or anything with alcohol content. It'd clear the dirt out a bit, though I am not very sure.

4) Or you could do what I did with my wireless Mighty Mouse. I took it apart. But of course, that one involved a lot of work and I obviously voided my warranty to do it. But it worked wonders for me.

I used a can of compressed air to blow the dust out of the scroll ball area. I did that both upright and upside down and with the ball depressed. That fixed it for me. Now I do that same cleaning every few weeks. It's been good.
