When I'm syncing content to my Apple TV, my Mighty Mouse scrolls like it's in slow motion. Though I can't confirm this, I'm fairly certain it happened once I updated to iTunes 8. I never noticed any problems until iTunes 8. I can use the trackpad on my MBP just fine, it's only the Mighty Mouse that's slow. Any ideas on what might be the problem or a fix? I went ahead and changed the battery in the MM and the problem persists.
