I was messing around with the different aspects of the integration of EPDM in windows explorer. I noticed the history button at the top and clicked it. A new History of the part popped up displaying the different versions, revisions, and info for that part. I tried to view a previous version...It then opens Edrawings, and once open displays the error "unsupported file type" for a sldprt file. Is this some setting that should be changed to a different viewer, if so what viewer? I thought with EPDM you could scroll through and view all previous history of the part. Is this option in a different location or is it just some setting somewhere?
