Acute3D viewer stereo

I am trying to use the stereo (quad buffer) option in the Acute3D viewer.  Set the parameters and turned stereo on but it does not display the left/right images.  This function used to work in the original Smart3D Capture viewer with  s3c files.  This was before Bentley took it over and revised/removed this functionality.  Has anyone used this successfully

I logged a service request on this over 1 1/2 years ago but nothing happened
