I launch Minecraft and head to the settings at the main menu to change it to Windowed Screen as I don't like playing in Full Screen (I have to manually change my system settings every time I launch the game so that I don't have to double-click my mouse to perform actions in-game, so Windowed Mode is preferable.) When I press Full Screen ON to turn it OFF, nothing happens. Then when I try to exit the settings, the game crashes.
