Hi,
For some reason my mouse won't scroll up. I like to use the center button a lot. It moves down fine, but if I want to go to the top of the page it wont let me.. Please help I am going nuts. It is the mouse that came with my mac, not wireless. Model # A1152
ed

System Preferences -> Keyboard & Mouse -> Mouse (tab/button)

Might find something under there for your mouse.

It might just be dirty, occasionally my mighty mouse refuses to scroll down so i just sit and swivel the ball around to get whatever might be caught out of it. That has always fixed the problem for me.
