Hi folks. I looked for the solution but can't find it. My iPad2, received in mid-April and trouble-free since, began having an issue on the weekend. It won't move from landscape to portrait or the other way around and it is not locked. I checked the button and I checked the setting. I have the smart cover. When I open it, it opens in the orientation I have the iPad in, either one, but again, can't change it. If I want to change it, I have to close the cover, wait a minute, then turn it and open it. Any ideas what happened and how to fix this? As I said, it's not locked. I double pressed on the home button and went all the way to the left to see the icon and it is not locked. Thanks.
