I recently upgraded from a Windows 98 computer with Autocad Release 14 to a Windows 2000 computer with both Release 14 and 2002 installed on it. After I copied my Release 14 drawings to both of these versions of Autocad I am no longer able to view the drawing previews when I enter the Select File dialog. This occurs now in both R14 and 2002. I figure this is some kind of Windows problems but haven't a clue as to what it is. Any ideas or suggestions?
