sorry Judy..
I dont know what the problem could be. Sounds like the margins are being somehow within the program. I have an occasional problem with photos that is just a baffling.
I may have already printed 50 or 60 copies of a page and suddenly the next copy of the same page does not have one or more of the photos! Start the next aseries of print jobs and all is well. This doesn't happen often, maybe a few times a year.
Isn't desktop publishing fun?
