[Zope] Ownership of ZClass methods in Zope2.2?

I have a problem in Zope2.2 - I've upgraded from a previous version, and there's a bunch of methods that used to work which now fail with access control issues (even when run as manager). My current theory is that it's because the DTML methods of the ZClass (or it's constructor method, which is trying to do some other funky stuff) is unowned. Hooowever, the DTML methods don't have an 'owner' type tab - should they? Worse yet, going to ...method/manage_owner, and clicking the 'Take Ownership' button brings up the Zope 'Help' window on Ownership. (this is netscape 4.7 on linux) Help? Am I on a total wild goose chase here? Anthony
