Would you provide more details? Firmware version? Are you talking about the TOC you get when you press the Menu button and then press the TOC icon? And which images no longer show where they used to? In the epubs when reading them, or in the Library or Main menu?
When I try the "Open with..." menu, I get two ereader programs; one for EPUB2 and one for EPUB3. My firmware is U633.6.1.1238. Might it be that you are using the wrong one for the epub you are viewing?
