Problem with DocProperty fields in the header in Word 2007

[Tom]

Hello all,

When I try to print a read-only document in Word 2007, the DocProperty
fields in the header and footer are blanked out.

Here is the scenario to reproduce this:
- Add a DocProperty field (e.g. Author) to the header or the footer of
a Word document.
- Mark the document as final.
- Open a print preview of the document.
--> The DocProperty field has gone blank.

If I try to insert another field in the header everything works OK. If
I try to insert the DocProperty in the body of the document,
everything also works as it should.

Is this a bug or can I control this with some setting?

Any help will be appreciated.

Best regards,

Tom
