OK, replying to my own post, I did just find a Workaround
that's only a few extra steps.....
After all edits and changes were completed in the Word file, I printed to PDF from Word,
creating a Rev A file. Once that was done and a new pdf was created, I opened the
Original File and selected "Combine" from the "File" pull down menu.
With both of the files in the same PDF document, I deleted all the pages from the
Original file. Page one of the Rev A file is now p. 1 of the "combined" file,
and all the PDF bookmarks (still there from the Original File) line up in the right
sequence. The bookmarks (produced by "Saving to PDF" with Headings 1 and 2,
when the original PDF was made) need to be re-linked to the pages in the Rev A
file, but that's quicker than starting from scratch.
Not really very elegant, but it worked. I'd be curious to know what's wrong with the
PDF files saved with bookmarks in WORD, because that happens EVERY time.
I have Acrobat Pro Extended, iteration 9.5.1
