Hi Erin:

Make sure you have disabled Tools>Options>Edit>Keep track of formatting.

Then go to Tools>Autocorrect>Autoformat as you Type and disable all the
options in there (you can keep the smart quotes and smileys if you like).

Then try again.  I think you are a victim of the Word "Automatically screrw
up your document" "Features" that need to be shot at birth :-)

However:  Word 2003 does have much more advanced styles and numbering than
Word 2000.  In the long run, it will pay you to re-create your complex
numbering schemes in Word 2003: you get extra options that provide greater
flexibility.

But turn off those Automatic eye-candy to stop it screwing up every document
you touch.  And make sure that Tools>Templates and Addins>Attach is NOT set
to "Automatically update styles on open".  If it is, it will break the
numbering every time you open a dopcument: turn it OFF :-)

Hope this helps
