problem with stereo mode

Hi again,

I'm having a problem getting into stereo mode.

I have two demo's. The first demo runs just fine.

The second demo involves manipulating the camera's location with a game pad. However, whenever I try to use viz.QUAD_BUFFER, I don't get stereo mode.

Here is my code:

Code:
##Name     :George D. Lecakes Jr
##Created  : October 11, 2006
##Modified : October 11, 2006
##Descr    : 	This program creates a viewport that centers around
##				the translational properties of an object similar
##				to that of a video game.
