>Is there something like this still available?

yep, it's documented in VB code in that help file somewhere. Here's what I did in my Preview form:

ThisForm.CRViewer8.EnableGroupTree = .F.
ThisForm.CRViewer8.DisplayGroupTree = .F.
ThisForm.CRViewer8.EnableCloseButton = .T.
ThisForm.CRViewer8.DisplayTabs = .F.
ThisForm.CRViewer8.EnablePrintButton = .F.
