When I opened a document that I work on every day (call it Doc 1.doc), I saw that one of my styles (Heading 2) has changed since I last closed that document. So I clicked Format>Style>Organizer and compared Heading 2 in Doc 1,doc to Heading 2 in my Normal.dot file. There was no difference. Here is the description for Heading 2 and it's identical to Heading 2 in Normal.dot:

Heading 1 _Font: 12 pt, Kern at 11 pt, Level 2, Outline Numbered, Automatically update

So in the Normal.dot list box I highlighted Heading 2 and copied it over to Doc 1.doc by clicking Copy. When I went to Doc 1.doc there was no change.

I've tried a number of things like redefining Heading 2 in Doc 1.doc. For instance, I tried copying Heading 2 from a few of the other documents over to Doc 1.doc but it didn't help. No matter what I've dine I just cannot change Heading 2 in Doc 1.doc. I can change and update all of the other styles in Doc 1.doc without problems.

I have several other Word docs that use the same style sheet (Normal.dot) and that do not have this problem. Some of those documents are at least 20 years old. I'm at a loss as to what to do next. (I am using Word 2000.)
