I noticed something very odd a couple of days ago. The trackpad button on my early 08 mpb makes a double click noise when i press it. i think its loose or something. its hard to explain very well, but when i press it a little bit, not enough to actually click the mouse, it clicks. sometimes its really loud, sometimes its not, but its certainly annoying. does anyone else have this issue, is it just me. also, is it enough to warrant a trip to the apple store
