Ok, I understand now.

 Actually looking at $ROOTSYS/tutorials/pyroot/shapes.py

 I observe the following -
 running directly

 $python shapes.py (in the mentioned dir)

 I see a nice canvas with all the mentioned shapes, and after  View->ViewWith->OpenGL
 I get an entirely interactive 3D opengl viewer window, but if I replace  Draw('gl') with Draw('ogl') inside (which I, probably wrong, assume  shall do the same thing
 as rawing on the canvas, and then going to view with opengl) I get a  "frozen" view I cannot manipulate. There's obviously some difference I  cound't grasp yet...
