[Zope-dev] Deleting versions from Control_Panel

For some reason, when I try to view the Version Management screen under Control Panel, I get a bunch of gibberish for one of the versions... And... it won't let me click on the check box and "Discard" it... Is there a way to do this manually? Or even see which versions are available manually? We are running ZEO, so I should be able to import Zope and go from there... --andy.
