My late 2008 MBP has been experiencing random times where I have to press down really hard (on glass) to get it to click. Obviously hardware related. It makes the "click" noise, but doesn't click on the OS. If I push harder, it picks up a click, but if I let off any pressure, it releases, while still pressed before it "clicks" back to normal. I'm going to keep using it until it's no longer random because I believe I'll have a hard time convincing Apple to fix a trackpad that is currently working perfectly at the repair center. I don't really care that much right now because I'm mainly on OSX, where tap-to-click works (unlike Windows... which only kind of works) Anyone else have this issue?
