programming in stereo mode

[Brian and Ruthie Dudley <brdudley juno com>]

Hello:
I am programming in GTK and GtkGLext using OpenGL.
I am trying to create a stereo viewer using stereo mode. 
I have an NVIDIA card with 2 monitors attached.
I am having a couple problems:
1.) The images in both monitors flicker.
2.) The images are displayed in the opposite monitors-- the eyes are
crossed :)
Has anyone had any luck programming in stereo mode?
Thanks for any help you could provide.
