I have a new UMBP 15" and just recently, without changing anything it seems. The pointer has serious issues moving around on the screen, especially in slow operation/movements it will jerk around and not stay where its supposed to be. If I just hold my finger in one place it will jump around very noticeably, inches even. Even clicking sometimes takes a few hard taps when just barely touching it would work. I've tried restarting and that didn't clear it up as well as changing some scrolling speeds. Just wondering if anyone else had seen this problem. Thanks.
