I\'m working on a basic iOS app which supports both portrait and landscape modes. When the iPhone simulator keyboard is open in landscape and I\'m switching the app
I am seeing the same problem. I believe the issue is related to the command key being "stuck" in the simulator if you rotate the device in the simulator using Command-LeftArrow and Command-RightArrow short cuts.
While we wait for Apple to fix, one way around this is to rotate the device by selecting the menu option instead of the keyboard shortcut. This rotates the device, and seems to leave the keyboard in a working state.
