Headers & Footers not visible in Word 2002

When opening an existing Word document in Word 2002 the
headers/footers are not visible & don't even print with
the document. If the same document is opened in Word
2000 or 2003, then it's fine. A new document can be
created & the header/footer will be visible, just not
when opening a previously created document. I haven't
been able to find anything about this searching the
knowledgebase and google. Had an Office expert review
the problem & he saw that the document settings were also
being changed, but couldn't make any sense of it. Anyone
else seen this and have a solution? Thanks!
