As of this morning, Jan 9, 2006, we have once again lost viewsets. In the past, this has been an issue when I changed workspaces as a team leader. GS did NOT fix this with the new build. I thought they had, so I blithely changed my workspace and boom! All my section and elevation quickviews vanished... unfortunately, I didn't notice until much later, after AC had overwritten any good backups.
Teamworks has some real flaws in it that makes working in it a white knuckle experience. So, with a deadline looming, I am once again redoing work. The Graphisoft corporate motto must be: "any job worth doing is wirth doing twice!"
