>Using VFP7 (SP1) I am calling a modal form from a modeless form. When I release the modal form control returns to the modeless form, but the main Foxpro menu suddenly appears, despite it being hidden previously. HIDE MENU _MSYSMENU gets rid of the menu, but has anyone any idea why it is appearing at all?

Use SET SYSMENU OFF to turn menu off pemanently. You can use it in combination with push/pop menu if you need to restore menu later.

push menu _msysmenu
SET SYSMENU OFF

pop menu _msysmenu
