[Zope] Again: manage_clone gives permission error since Zope2

Hi again! I still don't know what's wrong with my understanding of Zope, so I am trying again. My problem is that the Plutonia example (to be more precisely: the manage_clone method) is not working for me since our upgrade to Zope2. I get permission errors, although I am logged in as a superuser. I think at least the examples from the documentation should work. Help please! Floyd -- http://floyd.va.com.au
