Do they work properly in other Office programs?

Can you confirm that you are using Word 2003?

What happens if you start Word in Safe Mode?
· Hold Windows key + R.
· Copy and paste, or type the following command in the Open box, and then press Enter
· Note: There is a space between Winword and '/'.
· (The above may not work.)
· Or, try holding down the Ctrl key when starting Word.
· Then release the Ctrl key.
A window will pop up asking if you want to start Word in Safe Mode. Click on Yes and let Word open in Safe Mode. Use Ctrl+N and create a new document. Does this work?
Note that safe mode is not a way to operate Word on a daily basis. It is a diagnostic.
