So here is a strange one: I have a document that is scanned sideways. So to read it, I normally go into EZ PDF while holding the tablet in portrait mode, put the rotate lock on, and then turn to landscape mode. Works like a charm. Until today. I set the rotate lock to on, turned the tablet, and the image rotated! I left EZ PDF, and in every other app the rotate was locked--just not in the one app where I needed it to be. Tried rebooting, but same issue. Is this a bug in EZ PDF? What kind of bug overrides the rotation lock?
