For some reason I can not enter full screen by pressing Alt+Enter when running in a window, or pause the emulation by pressing escape when in full screen. Whenever I press Alt+Enter in windowed mode all that happens is my pc makes the critical stop sound. And when I Press Escape in full screen absolutely nothing happens. The only way I can stop the emulation or close the emulator while in full screen is by bringing up the task manager and ending task. I also want to mention that my graphics drivers are up-to-date. I will post screens of my graphics plugin settings below, along with a list of my pc specs any help with this would be greatly appreciated.
