i can t see any graph of sample code in lib of vpython
such as gas.py
my machine is under window 7 starter & 32 bit
and i install python & vpython specific for my vehicle from www.python.org

It is hard to tell what your problem is because you did not post any code that we could try to execute.

From your screenshot, I can see you are using a GUI interpreter (IDLE from the looks of it), and this can cause problems with wxPython since there would be 2 competing GUI threads. Try running from the command-prompt, not a GUI interpreter.
