?? bug -problem with history on new iPad app

I love the new App in general, BUT I have a new problem when reading.  The history tells the last page at which the book was opened, not the page at which I stopped reading.  Even if I tell it to go to the page at which I left off reading, it stubbornly returns to the last page at which I STARTED reading.  Does anyone else have this problem?  Can anyone suggest a way round it?  It's irritating and detracts from the joy o freading on the iPad.
