Hi Jill, this is what I am using to achieve the same:

Local oPreview, oListener
Do (_ReportPreview) With oPreview
oPreview.TopForm = .T.
oListener = NewObject("ReportListener")
oListener.ListenerType = 1 && preview
oListener.PreviewContainer = m.oPreview
Report Form stock_rpl Object oListener
oListener.CommandClauses.Prompt = .T.
oListener.PreviewContainer.oForm.WindowState = 2 

Cheers,

Luis
