If you want to automatically close your hidden main form, do not forget the form destruction in TAppForm.FormClose. Without the caFree, FormCount do not decrement and your application never terminate.

procedure TAppForm.FormClose(Sender: TObject; var Action: TCloseAction);
begin
//TRUE MAIN and this fake instance
Action := caFree; //
