The problem will most likely be in the MFC "Invoke" implementation.  You
should be able to set a breakpoint in Invoke, and see that Python is calling
it with just INVOKE_PROPERTYGET - not INVOKE_FUNC.  I suspect the MFC code
is not differentiating between being called with PROPERTYGET or FUNC -
Python needs it to fail.
