I think it might related to display resolution, as it works fine on my sons computer, which is set at 1440. My computer is 2160 and the "i" key does not register at all. I boot use Ctrl-Alt-Shift-P to load, to close I have from the taskbar as the "X" does not register on the keyboard. As a work around I use the Microsoft Virtual Keyboard, which works but seems to cause the mouse to lag for a few seconds
