I am using a brand new iPad Air and a MacBook Pro with Retina and on the Computer using Adobe Digitial Edition there is no possibility to jump forward/back using the arrows in the menu. It is not possible to jump to a certain page as well. The overall speed is incredible slow to switch between pages.
Exact same problem here - Win 7, ADE V3.0. - pages wont turn unless I click on the symbol at the top RHS of screen for Full/Normal size screen after Page Up/down or a click on the contents page.
Hopefully a bug or something, and not a 'feature' :-)
