I have a 10month old MacBook. About four months ago, i bought a trackpad cover for it, and so far it has worked like a charm. I just replaced it yesterday, and the real trackpad underneath looked the same as it did four months ago. But I'm having a problem with the pad. Three days ago, it hung up on me, and would not let the mouse travel vertically. The only movements were horizontal. I moved my finger around for a second or two, and everything was fine. It did not mess up for the rest of the day. Two days ago, it did it again. Same result: it seemed to fix itself. Yesterday, however, it did the same thing over and over again, fixing itself on regular intrevals. I can almost set my watch to when it's going to hang up now. I've noticed, that when it hangs up, it acts like I have two fingers on it; for instance, when I tap, I get a right click. When I move my finger up or down, instead of the mouse moving, the web page or whatever I'm in scrolls down. It does this for normally about seven or eight seconds, then everything is fine! I've disabled all of the options on the trackpad too. I disabled the accidental inputs, dragging, taping, and scrolling. Now the mouse only moves. But still it does this, except for now, with all the options disabled, it does not right click or scroll. Any thoughts?
