Is anyone else having this problem with the iPad2: 1. I close the cover on the pad when I am not using it. 2. After a few minutes when I try to use the pad again, I peel back the cover and the lock screen keypad appears...not the normal "to unlock, swipe here' version but the actual keypad where I enter my unlock code. 3. I attempt to type in my unlock code but the pad will not accept my key strokes. 4. The only way to resolve this is by pressing the home button and then the 'normal' lock screen appears with no keypad visible , I swipe the bottom of the screen and enter the lock code when the keypad appears and I can now enter my unlock code. I have the pad set lock after 2 minutes. This is repeatable. Strange but true. Anyone else experiencing this? IF so, any recommendations on how to fix this?
