When exiting Word 2003, MS Visual Basic Window appears with error message.
Message in MS VB window reads:
"Run Time error '91': Object variable or With block variable not set"

The "Continue" and Debug" buttons are greyed and "End" and Help buttons
active.
Clicking "End" button terminates program.

I have not automated a MS application or developing an Office application.
Used a workaround suggested by MS since Adobe Acrobat was not working.
