Joreen, there could be several things that cause what you see. Chief among
them is the pagination/text resizing capabilities of your ereader. You've
not mentioned what ereader that is, so I can't be more specific than that.
The way it works is that the ereader will react to the control information
that comes along with the ebook and its software - not Adobe's - will then
paginate the text according to its formulas. Some ereaders are capable
only of two or three different text sizes, while others can do more than
Other things that can cause 'improper pagination' include bad text in the
ebook (which you wouldn't see in Digital Editions because of the way it
displays the text) or something in the software of your ereader.
Just for fun, try doing a reset on your ereader and then open the ebook you
downloaded and see if anything has changed. Also, contact the manufacturer
of your ereader and find out if there's a software update available that
you don't have loaded yet.
Hope this helps!
