   Yes.  Create QApplication with PyQt (SIP) and try to create my
derived class of QMainWindow with boost.python, or vica versa.

  Yes, I've seen that error.   Tells you to create a QApplication.
That's not the error I'm getting under Windows now.   The error I'm
getting now is after I do app.exec_loop().

   I've seen the affect of making that mistake.   I'm not making it

   Thanks for trying to help.
