[pygame] pygame error unable to reset window for OpenGL context

[Astan Chee <stanc@xxxxxxxxx>]

Hi,
I know that I cant open two pygame windows in the same python app, so Im 
trying to get two pygame windows as a subprocess.
So what I have now is a main wx window that calls one pygame window via 
threading and another that calls another pygame window using 
subprocess.call .
The first pygame window is persistant but the second one is used to 
render and save images. That is why Im using subprocess.call .
So far, if I run it once, it runs fine. If I try to re-render using the 
same window, it gives me a "unable to reset window for OpenGL context" 
and this occurs when the pygame.display.set_mode() is called.
I was wondering what this means and how I can fix it? Is it because I am 
doing a pygame.display.quit() everytime I finish rendering in this 
temporary pygame window?
For references, the way I open a pygame via threading is like this : 
http://wiki.wxpython.org/IntegratingPyGame
and I create a temporary pygame window like this :

Thanks for any advice
Astan
