Per my previous message, Management Screen will not load - manage_workspace. Please disregard. The error was mine. We have a firewall & proxy access to the internet, but are accessing zope internally (class C local network). Recently Mozilla corrupted it's preferences - thus forgetting it's proxy settings. I thought this rule - disregard proxy for 192.168.* would work. It only partially works. Entering the complete address for the local zope server into mozilla's proxy bypass rule allows Zope's management screen to load completely. Thanks to all
