[Chimera-users] Chimera 1.5.3, nvidia quadro 4000 and stereo

The error "Error Initializing OpenGL: Couldn't configure togl widget" is 
because the graphics driver reported that it did not support stereo.  So 
either this is a graphics driver bug or a driver configuration bug.  The 
fact that it doesn't get the error with the 32-bit version of chimera 
suggests that it is a graphics driver bug and you should report the bug 
to NVIDIA.  On the other hand, the fact that you are getting a double 
image and stereo still isn't working suggests that the graphics driver 
is misconfigured.  Double-check that the "Stereo - Display mode" setting 
is correct for your setup.

     Good luck,
