Thanks for the suggestion David. Unfortunatley it looks like I already had that PDF option checked.
The document is about 200 pages, it's a novel. It was printed as a book a couple of years ago, and now the author would like to make several edits, and requested Word format. We are trying to keep the layout / page numbers similar to the InDesign document, but perhaps this is the wrong approach.
Regarding RTF format, I only see that as an export option when I have text selected. There are many many text frames in the INDD file, so not sure this would work. Is there a way to export the entire doc as an RTF in one go?
To be honest I don't think I'm going to solve this one, it seems like an anomoly. I have already started copying text from InDesign and pasting into word, using similar margins and page size in Word... that seems to be the best option at this point... kind of annoying though!
