aha!; thanks for the explanation.

Well, as you know, we have not officially gotten so far with 
implementing new style class features on our base classes (that is, 
unless you have checked in som extra code lately that relies on NSC)

Considering the time frame we are living with - yes, not using NSC is 
definitely the way to go for now, until I have time to upgrade to Plone 
2.1.1 and Zope 2.8 or 2.9.

Thanks!
