Hello Pete and Thomas,
I am unsure, but I recently updated my FSUIPC copy to the latest listed in the title. I am now noticing certain keyboard commands are no longer working in sim. I cannot zoom via +/-, “B” for altimeter doesn’t work, “Y” for slew does not work, and Alt+Enter does not work is what I have noticed so far. Even the GSX menu via Ctrl+Shift+F12 isn’t functioning, I have to open the menu via the menu bar drop down. I am able to control zoom and slew from a 3rd party instructor platform so I know it still functions in the sim. All my keyboard keys do work as I checked in notepad.
I googled around and it seems another user is experiencing the same issue. He fixed it by removing this version and going back down to prior build. Can you comment on this? I am sticking with 5.155 for now and am happy to test anything if need be.

EDIT: I can verify if I remove the FSUIPC.dll my key commands return to normal and all functionality is restored. I will await your reply. This is P3D v4.5.
