I got the same message on the St. Louis Metro list--but it was a file I could not open (MAC user)....and someone else on that list got the same thing. It was a different sender, however, than one cited on the Lunenburg list. I guess the lesson is NEVER open an attached file from someone you don't know (and sometimes from someone you do know until you ask first what it is, if you aren't expecting it or has a strange name or extension).
