You need to set _SCREEN.Visible to .F. to make it (and any forms running in the context of it) completely invisible, it'll continue to run as a background process. Once you do this, until you make it or some top-level window appear visible with a WindowState of 0 or 2, interacting with it will be probelmatic, so I'd look to have something minimize into the icon tray...
