Be careful with this as the user may have Word open for something other than
to modify a document generated by your application and they find it rude
that you force them to close Word to go back to your app.

Are they editing a letter that you want to store in a record displayed on the
active form?

The object reference remains (VARTYPE() returns 'O') but it is invalid.
Accessing any property or method or the RPC Server will raise an error 1426
that you can trap. Also, when a reference is invalid,
TYPE('loWord.AnyProperty') returns 'U'.
