Ah, I see your problem now. Ouch. I mostly deal with images and maybe some SWFs. I regret to say that I don't know how PDFs work in Lectora.When I publish, Lectora offers to delete unused images. Am I correct in assuming that this does not happen with PDFs? If they can't be removed at publish time, then I am officially stumped. This is beyond my normal usage of the program. Sorry, and good luck.Kevin
