Could you elaborate? Does clicking on one of the options under 'Table of Contents' not move you to a different page? I.e., If you click 'Chapters' then the first chapter should appear in the sidebar for you to select and open.
Fair enough. To clarify, once you enter one of the higher level categories from the home screen, the sidebar becomes the main navigation. This is because the lighter background will change to show the actual content with the links in the sidebar still accessible.
