[Visualpython-users] VPython mac os

Hi
Sorry for my poor English

I'm working with visual python under python 3 under mac os 10.6.7
I'm just beginning
I don't understand why scene.width and scene.height don't woks on my
computer
(If I change the values in the program nothing change)

from visual import *
scene.x=800
scene.y=120

scene.title='Thompson1'

scene.widh=800
scene.height=400
#scene.autoscale=0
#scene.range=(100,100,100)
#scene.center=(0,100,0)

balle=sphere(pos=(0,80,0),radius=2)
sol=box(pos=(0,-1,0), size=(10,2,10))

Regards
