My scroll ball stopped scrolling down so I turned it over and vigorously rolled it on a piece of white paper. Standard procedure as far as I know. Good news is my scroll ball works great. Bad news is both the right and left click now act as the scroll ball and bring up the dashboard. I had to dig through my closet and find an old Microsoft mouse that was usb. Is there a way to fix this or open up my mighty mouse? is the mouse covered under the warranty? I got the AppleCare on my iMac. Thank you for any help.
