I everyone, Anyone experience an iPad freeze while trying to navigate out of the Newsstand app? When I try to get out of the Economist to other apps or e-mail, my iPad freezes, and I can't even force shut-down. It doesn't occur all the times, but enough to be irritating. I have to wait ca 5 minutes until Newsstand unfreezes. I must not bathe only one in this case. Any solutions?
