Could people who have enabled Multi-Touch Gestures try something. Until now I have not had a single problem with my iPad 2 (other than a bit of back light bleed).. This weekend I upgraded from 4.3 to 4.3.3 and then enabled the "Multi-Touch Gesture" hack and since then I have had a problem twice which I have never seen before. Basically, the problem is that when the iPad is on the "Slide to unlock" screen, the touch screen is unresponsive.. If I double click on the home button to bring up the "music" buttons, they don't work either. I have now reproduced by letting the iPad go to sleep rather than switching it off.. In around 30-50% of cases, when you try and wake it up, the "Slide To Unlock" screen is unresponsive. Anyone else see this?
