When I open up certain word documents to view without making any changes to
the document, when I go to close the document Word asks if I want to save the
changes (even though there are no changes). It does not happen on all
documents, only some documents. (As a test - If I save the doc under a
different name and compare to the original, it tells me the two are
identical, so there really are no changes).

Any ideas about why this may be happening?
Thanks
