Hi all - I'm hoping someone can help me figure this out. I am using Acrobat Pro 8 on a Mac with OS X. I have previously been able to create bookmarks successfully in PDFs destined for e-publishing by simply following the directions. Now, seemingly without warning, when I click on the bookmarks icon, ALMOST nothing happens. By this I mean that the box surrounding the icon goes from closed on all sides to open on one side (as if it might open into a bookmarks pane), but no pane appears. There is nothing different about these PDFs and nothing different about my process. I am mystified! Can anyone give me a clue as to what is happening here? Thanks in advance.
