I'm stuck too -- specifically, when reading the contents of the book, there's too much text to see the link at the bottom of the page and I can't continue. (Love what I've seen so far though! I think making it full screen will fix the problem?)
I'm having the same problem.
It is already full screen (for me at least), I think the issue, as Jacic said, is that "enable scrollbars" hasn't been checked.
Sorry about that, scroll should be enabled now!
