Start game, mouse and keyboard do not work
No changes with anything and everything been fine for months, but suddenly last week could load game but mouse wouldn't click on buttons, sometimes can see mouse pointer but it won't click on buttons on screen, sometimes no pointer, could only get into game using xbox controller, press A it clicked on button and went to next screen, it isn't that though as it's been connected for months and was using it for flying only, could switch to kb and mouse at any time. That's all on my 4k tv, just last week or so been an issue with kb and mouse, but, if I switch to my acer monitor, everything works fine, and in full screen, then I could switch to window mode and it then works fine on my 4k tv in window mode, go full screen again mouse and kb stop working again, go to monitor, all ok again, no rhyme or reason to it and all the suggestions of this conflicting and that conflicting I don't think it's any of those at all, but still all a mystery, flipping useless.
