There are some courses in my iTunes U library, which, when I open them, go straight to the list of materials, with no navigation pane showing on the left, and no menu bar at the bottom of the screen. As far as I can tell, I have no way of getting out of the materials list. These are courses downloaded before I updated to iOS 7, if that makes a difference. Has anyone else encountered this? Or knows a way out? Thanks, Fz.
