After read others responses I thought that maybe you could use a actual Form object (via Define Class RepWindow as Form ) instead of a Define Window RepWindow. They should be the same to VFP. Does anyone else have anything to add to this approach?

WAIT … I just tried this and am getting a C5 error on the REPORT FORM line

RepWindow=CREATEOBJECT("RepWindow")
RepWindow.show(2)

REPORT FORM RepWindow TO PRINTER PROMPT PREVIEW WINDOW RepWindow

RETURN

DEFINE CLASS RepWindow as Form
	caption = 'RepWindow'
	windowstate = 2
*	visible = .t.
ENDDEFINE
