I just checked and my Overdrive was working fine from the Favorites menu, but I did have it in my right click context menu for my library list. So I removed it from the context menu and sure enough I ran into the same problem you experienced.
This isn't a problem for me because as a rule if a menu item requires you to select a book I put that menu item in the context menu. Bottom line is you helped me clean up my menu a bit since I would most likely never use the Overdrive plugin from the Favorites menu.
