Ko,

This was an intentional design change to the VFP7 product. The coordinate properties for _VFP and _SCREEN seemed out of whack. We changed it so that _VFP now refers to the VFP application window and _SCREEN references the desktop client area. The changes affects _VFP.Width, _VFP.Height, _SCREEN.Top and _SCREEN.Left. This gives developer more flexibility in managing things like toolbars. The NEWTBARS sample in Solutions gives a nice example using these changes.
