@Alan:<br>

I see a: "Extensions: GL_EXT_geometry_shader4" in my List. This is<br>
probably what you need.<br>
<br>
--snip--<br>
GEM information<br>
---------------<br>
OpenGL info<br>
Vendor: NVIDIA Corporation<br>
Renderer: GeForce 9800 GT/PCI/SSE2<br>
Version: 3.3.0<br>
--snap--<br>
<br>
And it should look like this, if you own a nvidia-GPU. Otherwise you<br>
will have to install the proprietary drivers.<br>
