Yea it was a bit short on detail, thanks for getting back anyway.
I normally run with the map on a separate monitor and that may be the problem. When I loaded a plane the prop was turning, switches worked but no 3D and once I selected Shift4 the cockpit detail disappeared leaving a totally blank panel and the system locked up.
Since my note I have discovered there is a dual monitor problem with Windows 10 latest update (which I had installed the night before Pb6) and for the present I have stopped using the second monitor and all seems to be functional. I trust there will be a patch or a work around from either Microsoft or X Plane soon.
