Hey guys, I'm having a bit of trouble with my macbook. (Actually, I'm having a bit of trouble typing this too, as you'll see why!) Everything is suuuuper twitchy, and rollover effects (like buttons, etc.) are taking up to 10 seconds to appear. I did the first logical thing and checked Activity Monitor, only to find this! Any ideas how to get my memory back? I'm guessing mdworker is the problem, and after a bit of googling I found it was related to spotlight, but I don't know how to fix the problem. I checked the spotlight icon, and nothing's being indexed... I don't know what to do! My poor lappy's almost unusable! Thanks!
