Word 2002/2003 and Styles

I went through the process a year ago of creating special numbering Styles for our legal documents in Word 2002. These documents are routinely modified by the CEO for new agreements, contracts, etc. He’s just got a new PC and it has Word 2003 (I have Word 2002). I’ve sent him the standard documents with the appropriate styles. When he opens the document, everything is fine. When he saves it, it completely changes all of the bullets and numbering styles that were in there.

I’ve tried opening the template organizer and copying the styles from the clean document to his normal.dot template. I’ve tried copying his old normal.dot template from his old PC to his new. I’ve tried copying my normal.dot template to his PC. Nothing seems to be helping. Any other ideas?
