I noticed that the values shown in the screen sometimes are correct, but sometimes they are wrong.
It looks like the value is reseted to zero, but the 3D view stays the same, losing the reference.
Is there any chance of customizable colors for each eye in conf.ini.
If so, we could test another color scheme like Trioscopic or optimize the red and the cyan to our glasses.
Maybe even reach the color of INFICOLOR scheme.
Thank you so much, Pablo. 
Merry Christmas.

Santo,
I've reviewed different things for what is going to be the V6 of the MOD, and I hope the final version. The changes in V6 respect of V5 are:
-Implementation of Convergence in Stereo view. It allows deeper stereo perception with less eye strain. Now it formally follows the convention of considering positive values those ones that cross your eyes "clockwise, port, right, inward or however you want to express the direction" and negative ones the oposite.
-Correction of a mistaken way of alternating the eye shift that at the beginning caused some troubles with Convergence, but it was a problem in Separation not noticeable before.
-Fixation and different way of determining if the plane is seen in external or internal view. This makes fail safe the adjust of Separation.
-Reviewed some complaints made by Santobr regarding incorrect adjustment in flight.
-Extra precision to adjust Separation and Convergence.
-Established mechanism to avoid freezing of the game when switching to Mode C and your video card doesn't manage Auxiliary Buffers. Now in the worst case you will not see stereo at all but the game will keep working.
Using this version with Convergence Adjustment, I realized that after having set the Separation is more importante to be able to adjust at any time convergence, so I established this new setting that allows you to have Convergence as default:
[Mods]
PAL3DAdjustConv=1
The default value is 0, it means the old fashion operation that when the game starts you can change Separation until in non-Stereo Mode you switch to Convergence adjustment. But with PAL3DAdjustConv=1 the game starts adjusting Convergence instead and you have to switch to Separation if needed (less needed now, that's why I offer this chance).
As a wrap up of all the current settings until now, this is the list with the default values:
[Mods]
PAL3DStart=1
PAL3DSeparation=1.0
PAL3DSeparationExt=25.0
PAL3DConvLeft=0.0
PAL3DConvRight=0.0
PAL3DAdjustConv=0
PAL3DScrShtDir=MyScreenShots/
PAL3DScrShtExt=jpg
PAL3D6DOF=1
PAL3D6DOFAutoReset=0
PAL3DEcranWide=0
Regards and Merry Christmas,
Pablo
