Hello,
Sorry to dig out this old issue. But I ran in the very same problem on my
laptop, though it works fine on my desktop.
After some investigation, I found the *culprit*. It's in particle.py, at
line 174:
pic = pyglet.image.load('fire.png', file=pyglet.resource.file('fire.png'))
This is a class attribute, and gets executed at import, before
director.init() had a chance to run. Still it's annoying that I need to
initialize the director before loading images like this as class attributes.

Open GL contexts are not supported by your gpu drivers, (because by default
pyglet builds a hidden window that will share context with all the windows
created by pyglet window.Window)*"
So I will now try to figure out what pygelt does when calling
pyglet.image.load. If someone with more experience with pyglet can point me
in the right direction, I'll appreciate. I'll get back to you if I find
anything...
Daniel.
