It worked really. But what is the root cause of this problem.if the available space was not good enough,the Pad should go back to it's original status.it is like, you go to a blind alley in a car, and there is no road ahead, then car should retrace it back wards in reverse mode. Apple designers must look at it. The designers should think that I am a home
Maker and I use the pad to keep me connected to the world.
Any way thanks
