Hi smf
I am using 1.1 and an iPAD 2. I get the occasional problem of a file failing to open it reports a problem, second time the file opens but the top menu bar is funny. This is usually after I have been to the store or used shelf view. I totally power down the ipad, open scorch in list view and try not to use any of the other features. It seems to behave for a bit then.
