Hello zy... & thanks for replying.

Um, the problem with your opening gambit is that under the restriction a user has no access to Styles. Hence...!

Presently, I am working on a copy, as you suggested, which I made as follows:

1. I opened an earlier version of the document and saved it, with complete text, etc, as a template.
2. I deleted all the text and saved the template again, leaving me with a new blank template per the original.
3. Opened the new template,
4. Copied the text to the new template.

Or at least, that's what I THINK I did. (When troubleshooting, I tend to get lost.) Anyway, it seems, so far, to have worked—but as I don't trust it, I am presently doing a "pseudo-edit" (a complete read through, just to make certain that every character is where it should be).
