Surely, there is difference :)
I created ZClass with this box unchecked, without any other base classes.
Then I can't instantiate any object of that class. (However, when I
selected base class 'DTMLDocument' I can make an instance.)
If you can't reproduce this behaviour, then maybe it's a symptom of
'boolean property bug' ? (If so, you can apply patch for it, posted by me
some time ago).
