I havent looked at your code for lack of time but I thought I'd
mention that you should ensure that renwin.Render() is *never* called
before your wxVTK widget is _realized_.  If this ever happens your VTK
window will not be embedded inside your wx widget.  In other words,
you must call renwin.Render() only after you have shown the wxVTK
widget on screen.  I suspect that this might the source of your
problem.

BTW, did you notice the expose related problems with wxPython.lib.vtk
that I mentioned in my last email?
