I tried importing UG files into 2008. Both drag and drop and using the Open command caused an immediate CTDT. At the root of it is that SW seems to tell the OS that prt files are SW files which I guess is to keep compatibility with SW95. Maybe for extensions with known multiple personalities they need to have a little more software ettiquette and ask whether you want SW to handle prt or leave it alone. Strangely, the other day dragging and dropping was working just fine unless I did 20 at a time. TOP
