It would seem that you are applying styles to the text when creating the word document...correct?
Instead of applying the styles to the text in Word, do this:
Type the word document as if you were creating a regular document, but do not apply any source coding such as headers, etc. Just use regular text. Youcan use the bullet-ed feature in Word, but don't apply any additional markup to the text.
Import the document into Dreamweaver...
Cleanup the Word HTML...
Then apply your source formatting...using Dreamweaver.
Let me know if this suits you....otherwise...back to square one.
