Hello Bill ,
OK,try in the VFP main menu View option and then General Options,here click Replace and Top-Level Form.
Now ,you must have a form AS Top-Level Form and you could upload your menu in the Valid procedure (or from your obiect)
with the following command (same to yours with a minor diference): DO your_menu_name.mpr WITH THIS ,.T.
I hope you manage.
With best ,
Cosmin
