Cool!

Please follow the instructions that I posted previously, your code 
should then be equivalent to this:

    def __init__(self, parent):
        self._init_ctrls(parent)
        
        self.diagram = wxDiagram()
        self.diagram.SetCanvas(self.scrolledWindow1)
        self.scrolledWindow1.SetDiagram(self.diagram)

As the Boa application help says, you should not add code to the 
methods that Boa generates and maintains; the _init_* methods.
In the help you are also encouraged to make your the changes
in the __init__ method after the self._init_ctrls call.

Add this snippet of code to the bottom of Preferences.py

try: sys._wxApp_Cleanup = wx.__cleanMeUp
except: pass

to fix it.

Learning to use CVS is of value to any developer IMO. 
Boa is not released that regularly, so if you need support for the 
latest wxPython or new features/fixes then it's up to you to learn CVS.
There's plenty of help on the web and in the Boa application help.

I do suggest leaving it until you are more familiar with everything.

You can have more than one Python installation at a time, but as I 
said, this is a last option.

Boa 0.1.0 was developed on wxPython 2.3.2 and Python 2.1, so that 
is where it will run the best.

That said, you now have the major hickups of 0.1.0 patched so you 
should be fine.

Best advice I can give would be to make more use of the SourceForge 
tracker and the Boa application help. 
(esp. Docs/boa/apphelp/MixingSource.html). 

Learning Python/wxPython should be fun, so enjoy it!
