Thanks for the tip.  Deferring the call to Render gets the image in
the wx window.  Good.

But now, out of the frying pan and into the fire.  Any mouse event on
the image completely bombs X windows.  Not a freeze like I was
experiencing under the CVS wxWindows, but actually kills X windows.
All these events are controlled by the Interactor.  Any advice on
whether I can hope to get Interactors working under wxPython?

The interactors are set up with:

         self._InteractorStyle = vtkInteractorStyleUser()         
         self._Interactor = vtkRenderWindowInteractor()
         self._Interactor.SetRenderWindow(self._RenderWindow)
         self._Interactor.SetInteractorStyle(self._InteractorStyle)

I haven't done it yet as I have been busy dealing with a gazillion
problems, but it's on my list.

Thanks,
