Hey guys. My Trackpad on my second Air (first one replaced due to loud fan and wobbling) is a bit strange. It has "dead spots" where it doesn't register touches. I've tried the other airs in store and they have this issue, but my air sometimes in a place right in the middle of the trackpad, it doesnt seem to register my finger and doesnt move the track pad. It's very frustrating. Any ideas and or other people who have this issue?
