So what should the Windows XP/Outlook users do about their "Broken Clients"? I read the recent thread mentioned below about "Configuring MIME content-types" and went into MS Explorer/File helpers and added the .dwg extension to the list with a reference to AutoCAD R12 MAC which I have on my computer as a standby and it runs in Classic mode, But I use AutoCAD 2000 in Virtual PC on OSX daily.
