Digital Editions Will not turn pages unless resize Computer window.

[giantsarge]

I am trying to use the AP statistics book "the Practice of Statistics, 5th Edition" in my classroom, and Unless I resize the window of the Digital Editions, the page will not turn. You can not even put a page number in or use table of contents, unless you resize the window every time you want to change pages. Technology guys for district have looked at it, and asked me to find out from Adobe. Can Someone help.
