Matt, Good question - I have some old Pro/DESKTOP files as well. I added the config.pro options topobus_enable yes intf_in_granite_direct_enable no This should work - but I am not currently having success with it. The files are in Intralink though, so it may be a culprit. I'm not certain how old the files are either. If they are pre-Pro/DESKTOP 2001, they are not based on the Granite kernel, so this may still work for you. Regards
