A problem has cropped up this week. When searching for a file the extensions for AutoCADD .dwg don't appear. All other extensions seem to be there including the .bak extensions for the backup files for those same ACAD files.
I am using AutoCAD LT 2008 with FusionWare on a MacPro computer. I recently downloaded DWG True View and Autodesk Design Review 2012. Could this have something to do with it?
