My custom order entry program has a Customer ID field.  The Edit Icon shows the list of customers and allows selection of a customer.  If the customer does not exist and the customer ID field is empty the Edit Icon will not popup the New Record screen.

Screen Properties are set to true for AllowAddNew and AllowEdit.  AllowAddNew is not working.

Is there something that has to be set on the Customer side to allow add new from my Custom program?
