DCS CTD/Frozen When Entering Mission Menu w/Multiple Client Options While Using MFD Viewports

[Dawgboy]

I'm trying to determine what I'm doing wrong with this monitor configuration:

=====================================

_  = function(p) return p; end;
name = _('DawgboysMFDExtraction');
Description = 'MainView on top; LMFD and RMFD to the right'
Viewports =
{
     Center =
     {
          x = 0;
          y = 0;
          width = 3840;
          height = 1080;
          viewDx = 0;
          viewDy = 0;
          aspect = 32/9;
     }
}

LEFT_MFCD =
{
     x = 4125;
     y = 0;
     width = 900;
     height = 730;
}

RIGHT_MFCD =
{
     x = 5390;
     y = 0;
     width = 900;
     height = 730;
}

UIMainView = Viewports.Center
GU_MAIN_VIEWPORT = Viewports.Center

===========================

Clean install, no mods. It works fine when I start the Viper in Instant Action or Fast Mission where there's only my aircraft as THE only client flying option.  However, if I go to a joint mission where I have a choice of aircraft to fly, in this case F18/F4/F16, DCS freezes the entire PC, or, DCS CTD.  Usually, it locks the entire PC until I restart it.   

I have the main monitor as 3840x1080 on the left, with two smaller monitors to the right, 1360x768, with all monitors in landscape mode.  

I have not tested this in MP mode, only SP, and again, it works fine when I enter the Viper, which is the only flyable option with that as the only one client aircraft. 

I'd appreciate any ideas and help.  One option I might try is giving the actual main monitor resolution for the "aspect" variable and test.  

Thanks!

UPDATE: Tried aspect = 3840/1080, which was slightly better...did get to make aircraft choice, but it still froze, followed by CTD.
