[Paraview] Graphic window disappears using: pvpython sphere.py

[pat marion]

A few more notes-

If you use the script I just posted, make sure the interactor is initialized
before the first call to render- it must be initialized before the opengl
window is created.

In the current version of paraview, it is not necessary to call Connect(),
this is done automatically when paraview.simple is imported.

It's not a good idea to include the line:  'from paraview.servermanager
import *'.  You should just access servermanager methods via the sermanager
namespace that is created when you import paraview.simple *.
