Thanks for the replies but...

I have the most current version of activesync (2.4) but have reinstalled it anyway.
I have tried reinstalling the e-books.
I tried doing a soft reset on the Axim (actually I have to when the e-book hangs)
I though book size may matter but there seem to be a weak correlation at best.
Examples: the book "Ideas" @ 1.80 Megs does not open well
The book "Ben Franklin" @567 KB opens with no problems
The book "Sick Puppy" @343 KB does not open well
The e-books in question will often hang if I navigate to Microsoft Reader and open the book from the library.
The books seem to open better by navigating to the e-book file and opening the e-book by clicking on it (but it is not 100%)

Previously, I stored the books on a CF card, I tried storing the problem books in main memory, but this seems to have little effect when opening from library of Microsoft Reader.
The books do seem to open somewhat better when installed in main memory and the e-book is opened by navigating to the individual file.

Again I appreciate you advice.
