Launching Python debugger from embedded Python

[Stidolph, David]

I'm getting my company to register for PyWin so we can get the debug
versions of PyWin, but in the meantime I made a release version of our app
to test it out.  I have the following code that is called from a Menu
operation in our own ui:

  def OnMenuDebug(self,x,y,flags):
    print 'OnMenuDebug'
    import pywin.debugger
    try:
      a = 1 / 0
    except:
      pywin.debugger.post_mortem()

In the Output Debug Window of MSDev, I can see that the win32ui.pyd is
loading, and it loads other DLL's, but it crashes.  I'm going to do another
release build with all the debug info turned on, but wanted to get this
question out to see if anyone has ideas to get the debugger working.
