FlyjSim Q400 Transponder

In the past couple weeks I had an automated Win10 update which messed up many of my X-Plane multi display settings (I have 3-1080 displays) which were working well prior to the update. I had to redo all by settings in X-plane.  I also noticed the transponder knob for the FlyjSim Q-400 does not respond on mouseover I get the indication it should work, it turns but when selecting the Transponder Lsk the numbers do not change. It will change from "Off" to "Stndby" and "Active". I turn the knob in all directions - no change from "0000". The Lsk button works and so does ID button.  I have also attempted to try the fmc Rad/Nav and cannot change the transponder there either.  I have not experienced any other issues with the Q-400 since the update. I also have Pilot2atc running - Transponder never did interact nor does it now - same with my Saitek Radio stack, never did interact - BUT I could set the transponder in the past.
