Hi Joe,
I'm running x64 Ubuntu 8.04 with a GeForce 8600 GT and the NVIDIA
driver. The two required extensions are reported by gl-extensions,
but the spheres doesn't work.
Running spheres gives me a black spheres window and a popup window saying:
An error occurred while drawing the world T{ world f ~array~ ~array~ f
f ~vector~ ~array~....
This world has been deactivated to prevent cascading errors.
framebuffer incomplete (missing attachment)
:d
