Thanks for all of the replies. I definitely agree LyX is awesome! But just as I don't want to learn+buy SWP, my colleagues do not have the time to learn LyX. We must use SWP for the master/working copy (not just on this project but on a couple of them).
I'll look into why SWP does not like LyX latex output and see if I can't figure something out. As for the question regarding paragraph 13, I have not figured that out yet. I need to investigate whether the error is related to "paragraph" or line 13. And whether blank lines are considered paragraphs. I'll let you know what I discover. Ken
