If you are using vtkPanel, you need to make the panel render to update 
the pipeline.  The easiest/safest way to do this is call repaint() on 
the render window.  If you get flashing on your render window, get the 
latest vtkPanel out of cvs - I made this work in November 2002, so if 
your version is older, you should get the cvs version.
