i picked up a new 13" MBP. It worked like normal for a couple days, barely used though. Now I get it out and I have no click on the trackpad. Tap to click works and I can move the curser around, but a press does nothing, I didn't see anything it setting, but I don't feel any click either which I thought I did before but could be wrong. Am I missing something? Or did I get a lemon?
