Weird thing. Clicking on settings I no longer go to the screen where I can change the keyboard commands etc. The "Pause" word in white letters comes up and the game darkens a bit. Also on the right lower side of the screen a check-mark and an "X" show up but clicking on either of them has no effect. The only way to leave is by pressing ESC. The biggest thing is that it is happening the same thing when I load Trainz 12 but the game has to be terminated using task manager because I can't get any button or mouse clicks to leave the screen. I suspect that it has to do with the screen resolution or with the font size. I was playing just fine at 4K but now this happens. :'(
