just bought an ebook that only opens with digital editions. Find it pretty useless on a surface tablet, and very disappointed. Can open normal pdf files on the reader and swipe to turn pages, zoom with finger motions, and read in portrait mode like a book.
With this program, can only turn pages by the tiny scroll bar on the side or with a keyboard (which means I have to view a book in landscape mode), make clicks with the mouse to zoom only to predetermined sizes. Awkward and pretty much useless for reading anything.
Suggest adobe add digital rights management to their free reader - its a usefull product. this one is a dinosaur.
