Bill,

see if this gets you any further (Vfp6 SP3)
_Screen.ActiveForm.Top shows -4 over here. I still see the form caption

#define	FORMCAPTIONHEIGHT	;
	iif(empty(obj.TitleBar), ;
			0, ;
			iif(obj.HalfHeightCaption, ;
				sysmetric(SYSMETRIC_HALFHEIGHTBUTTONHEIGHT), ;
				sysmetric(SYSMETRIC_WINDOWTITLEHEIGHT) ;
			) ;
		)

local obj
obj = _Screen.ActiveForm

local _height, _width
if( obj.Desktop or obj.ShowWindow = 2 )
	_height = sysmetric(22) 
	_width = sysmetric(21)
else
	_height = _screen.Height
	_width = _screen.Width 
endif
_height = _Height - FORMCAPTIONHEIGHT
obj.Height = _height
obj.AutoCenter = .T.
