[Zope] ZClass inheritance and properties

Using version 2.3.0, and adding ZClasses strictly through the management interface: I defined a "virtual" ZClass with some basic properties and methods that I wanted included in other ZClasses, and inherited from that. The properties were defined in a propertysheet I named "default". In my derived ZClasses, I seem to be inheriting methods, but not properties. I can't programmatically set them, nor can I view them through the management interface. Is there something I'm missing? -John Daily jdaily@progeny.com
