[Visualpython-users] upadting vpython 4.x problems

[Symion <sy...@pr...>]

I've just installed python 2.5.2, no worries.
I then installed Vpython 4.beta.26, no worries.

 From IDLE I run stonehenge.py (standard test program).
After a fairly long wait, the scene window pops up and vanishes and the 
program ends without a trace and puts me back into IDLE.

Same problem for all vpython scripts.
Tried running standard python programs, no worries!

Switched on DEBUG.

Before it dumped me back into Desktop, I saw something about Numpy? and 
a Windows Error.

Can anyone help?

Cheers Symion
