When I search for words in my Word 2007 DOCX file, Word doesn't find words that are definitely there. I think this is because the "Format" is "Outline" (that is, the Find dialog says "Format: Outline".) When I search it just returns "word has finished searching the document. The search item was not found."

How do I get out of this "Outline" format? (Note: Occasionally, I'll open a DOCX file and Find will not say "Format: Outline" and search will be fine. But usually it's in that "Outline" mode and I can't get out of it.)
