#4 it is.   I have used the PMDG 737 for a looooong time now and never had issues with it.  For me, it was issue #4.  Turn off the logging garbage.   It also stopped the other bug.. the sim would load in almost instantly with the PMDG as my active plane and NONE of the scenery would be loaded yet so the 737 would shoot off across the ground, bouncing along the way at full speed while all the mesh, textures, autogen slowly loaded in with the plane in full powered up mode despite me having told it to load in a SHORT panel state.   Turning off both logging features put a stop to both issues.  Thanks for the response.   As usual, PMDG is tops in support and aircraft.   Peace!

If one AFCAD is devoid of Apron/Taxi point and the other has only Taxi/Apron points then the two could work together but if both the one add-on AFCAD and the MyTraffic AFCAD have taxi/apron points it is going to cause a train wreck of AI traffic problems.   It is generally undesirable to have more than one AFCAD file in place.  It's just to much of a pain to manage.   MyTraffic should have supplied a fully replacing AFCAD instead just a partial 'overlay' AFCAD.
 
But technically, as F70 states, you could have multiple AFCADS that only have specific parts compiled in it then combine all the BGL AFCAD files into one AFCAD folder and the would work together but if any of them share the same data, the higher priority wins and the lower priority is just causing a headache now.

SOLVED:  Switched VoxATC to Above Normal priority and set it to use Cores 0,1 and 2 instead of 1, 2 and 3 in the advance settings.   It is no longer pausing and is working as it should, minus the continuous handoffs to center that have plagued it for a while now.

Well it's not free anymore.  That was 8 years ago when it was in development.   It's full blown internet suite now and I have good luck with it.    All has ended well.  I went into the virus Vault and all the files were there.  I told it to restore all the files, re-ran the 2.3 to 2.4 installer, followe Rob's guide on getting all my addons to work again in 2.4.   I am up and running with seriously smooth performance.      A fairy tale ending.  Yeah!

I guess it helps to read the manual sometime doesn't it?
