The building process of vpython was successfull. Also my project was
running without problems. The only problem was the control window and the
box in the second scene.
If i comment the box-create line and uncomment the controls it works.
If i uncomment the the box and comment the controls line it also works.
Both lines uncomment - seg fault.
(The code is only an excerpt of my project)

Thank you for your patience and sorry for my bad english
Sebastian
