Is there anyone out there familiar with a workaround for version 2009 loading assemblies as lightweight? I have all of my options set appropriately and my assemblies still open in lightweight. That is a problem because some of my properties in my bill of materials do not get updated. The SolidWorks response was to either do a hard re-load (ctrl-q) or update to sp 4.0. We have cut costs at my company so we dropped the agreement. I heard that there is a registry hack that will take care of it. Please help!!!
