Changing PlugIns.py, line 145 from

    manage_main = DTMLFile('www/main', globals())

to

    manage_main = HTMLFile('www/main', globals())

(make sure you've imported HTMLFile too)
restores the behaviour of ZPatterns-0-4-3b2.

If you try adding any normal ZClass in a normal folder, you get the
behaviour that you're reporting as a bug for ZPatterns-convenience.

Therefore, I reckon the original behaviour with ZPatterns-0.4.3b2 is
incorrect, and the behviour with ZPatterns-convenience-release is 
consistent with how ZClasses work in the rest of Zope.

If you're not happy with the behaviour of a_zclass_instance/manage_main,
then that will need changing for all Zope and not just ZPatterns.

Stick a report in the Collector perhaps?
