Hi,
The procedure works fine for me. Double-check your spelling. Also, are you using the procedure to close the document or are you running the Close command from Word? If you do the latter, you'll still see the dialog box asking if you want to save changes. For my technique to work, you must close the document by running the VBA procedure.
If you're still having troubles, copy the entire procedure from your document and paste it here so that I can see it.
