>But with the window not dockable, it can't be moved outside the VFP main window. I have the four windows on a separate monitor to have as much room as possible in the main VFP window for developing forms, etc. If they are not dockable, they can't be placed on that separate monitor. I'll have to see about moving the entire VFP main window across the monitors.

Unfortunately dockable windows only supported with _screen, not with user defined main forms. Rubbish... :(
