How is it when I DEFINE WINDOW with GROW, FLOAT and then REPORT FORM PREVIEW to that window I cannot resize or move the window?

My goal is to have a floating print preview window outside the VFP forms

DEFINE WINDOW PrintPreview FROM 10,10 TO 50, 50 IN DESKTOP TITLE ;
	THISFORM.Caption + " Preview" CLOSE FLOAT GROW MDI ZOOM

If Used(this.parent.grd.RecordSource)
	this.parent.createheader()
	Select(this.parent.grd.RecordSource)
	ACTIVATE WINDOW PrintPreview
	Report Form (this.Parent.strreportname) PREVIEW IN WINDOW PrintPreview
ENDIF

RELEASE WINDOWS PrintPreview

TIA
