Thank you! dwanthny, your method worked! Kovidgoyal, rebooting still did not solve the problem
I suspect the secret is:
A. combining the books
B. Save cover separately - I personally think this should be the default and you should
uncheck if you
do not want covers included. For those of us who are a little slow, that would be a little more explicit.
Again, thank you for an incredible program and helping so quickly!
