Hello all. About 3 days ago I noticed that right clicking on items was becoming increasingly difficult to do. The system would only register about 75% of my right clicks. Later that day the left click stopped working almost entirely. When I go to drag items, I either get no response or the pointer will grab the item briefly and then let it go after moving a very short distance. It does seem to work when I put a significant amount of pressure on the trackpad when clicking but I've seen some horror threads about trackpads cracking so I'm attempting to avoid applying too much pressure. After doing a few Google searches, I found a couple of threads on Apple Forums with people describing similar problems. I have read a couple posts from users saying tightening a screw underneath the trackpad has worked for them. While it seems like an easy enough process, I made an appointment with the genius bar to avoid potentially voiding my warranty. Anyone else experiencing similar problems or know of any possible causes/fixes? The idea that a screw has come loose seems feasible considering that it does seem to work if I press hard enough. I dunno...any thoughts are appreciated.
