OK, that's just a wxPython-level warning. I guess I'll have to remove
the Dabo-level property that accesses it.

Yeah, someone else had mentioned that. I'll have to spend a little
more time investigating what is different on my machine than what I
wrote in that document.

The problem is that in order to find all the classes involved, Dabo
looks into the directories off of its Home Directory. It assumes that
there is a 'biz' directory that holds the 'biz' module for your app;
if not, self.Application.biz will be None instead of a reference to
the biz module.
To fix the error, I need to know a) if you followed the standard
directory structure (i.e., what dabo.quickStart() creates), and b) how
you launched your current session.
