Has anybody here had any problems with palm rejection with your flips? I just got the flip 14 a week ago, and everything's been going smoothly with my active pen, but today it started acting funky... It works just as before when I don't touch the screen, but as soon as my palm rests on the touchscreen it becomes very jittery flying all over the place and registering frequent clicks when I apply pressure. I've tried restoring, using sony's touchscreen calibration tool, but I can't get it to work properly again... Also, every once and a while palm rejection works, but when I lift my hand away and bring it back it's gone again. Very strange... If anybody has any suggestions on what I can do I'd be more than grateful. Been trying to find some sort of driver I can try but I'm having little and disorientating luck.
