6.2.1 Upgrade - Workspace contents missing in C-View

I just upgraded from 6.2.0 Windows host to 6.2.1 Windows host.
Everything looks fine, except I have nothing in my C-View (but it is all
in the system builder view, what I don’t like, but that was the same wit

Is there any simple trick to bring them back there? And why is the Item
browser per default in the C-View? I know I can remove it, but sometimes
my workspace needs some reset (ok, perhaps not in this new version) and
the 6.2.0 resets where pretty nice, this one is not.
