I have another quirky problem with Heading styles with the Hidden text attribute. Sometimes they show up in the Document Map and sometimes they don't.

I was about to upload two sample documents, one with them in the Map and one without. Then I discovered, that closing the document and reopening it caused the one with them not in the Map to reappear. I tried this on a couple of documents, Closing and reopening fixed the problem at least for awhile.



Any clues as to why they go away, then come back on a reload?

I would expect hidden headings not to appear in the Document Map.

In Word 2010, I haven't been able to reproduce any inconsistencies, assuming of course that the entire heading, up to and including the paragraph mark, is formatted as hidden.
