I was searching games in the App Store and when I clicked on one it came up as LogMeIn Inc. I can't close it and it won't go away. I can't access anything in the App Store now. I also can't seem to control my restrictions in the general settings.
When you tap on a an app entry in the store it opens in a white overlay window in the middle of the screen, to close that you should be able to just tap outside that overlay window's boundary, on the background of the store above or below it.
