I've had the new macbook pro for about 3 weeks without any problems. Today, my mouse and trackpad started behaving oddly. The curser constantly skips a bit to the left or the right and randomly clicks on the screen, regardless of whether the mouse is plugged in or not. Obviously, this can come tiresome quite quickly. I've tried restarting the computer and tweaking the settings, but nothing seems to work. I'm also up to date on all the software updates. Any help would be greatly appreciated.
