Techie question for the groupmind.

I have an iPad. In order to reduce the amount of paper filling our house, I've started getting my magazines on the iPad Newsstand. Except it's acting up.

When I tap Doctor Who Magazine, the DWM logo appears for a moment (or longer than a moment), and then I bounce back to the Newsstand menu, The last time this happened, I fixed it by restarting the iPad. Tried that.

New Scientist and SFX both working fine, by the way. It's just DWM.

Any thoughts?
