My Magic Mouse which has functioned flawlessly up until now, has stopped swiping. When I turned the computer off last night it was working, first thing this morning I noticed the swiping doesn't work anymore. I was really beginning to like being able to go forward and backwards on pages with the two-finger motion. Can anyone help ? I am taking my iMac in to the Apple Store in January for yellow tinge problem, so I can just add this to the fixes. Everything else runs great and I do love my iMac. (i7, 27", 2tb drive, 8 gb RAM) I am not real computer savvy, just use CS4, Aperture, Safari, if anything goes wrong with the hardware I am lost.
