Only fails when doing a Married Couple config where referring to them as Mr. and Mrs. Lastname in the address and Firstname and Firstname in the Greeting Line.
Address sets up as needed. (Mr. and Mrs. Lastname).
Greeting line (need to set as: Dear Andy and Mary).
Nearly as soon as the GL is altered, in this window, Word freezes and then Grays-out where requiring it to eventually be forced closed.
Default GL works fine.
