Mighty Mouse Scroll Wheel

Hi Gang

How's everyone doin?

I suspect the tiny little button wheel in the middle of the mighty mouse is not working properly? I can get it to scroll upward, but not downward. And it does it's job as it goes from side to side. Just can't get it to scroll downward.

Time for a new mouse with scroll wheel?

BTW - went to system preferences everything's checked there correctly.

Thanx guys
Mike

Hi-

The scroll balls get gummed up with dirt and skin oil.
There are a few ways to clean it, as this search reveals:
Clean Mighty Mouse.

Start with the paper strip tick, then move on to disassembly if necessary.
