My mouse is configured as a left-handed mouse. Every application I run on my Windows machine works this way, except Divinity Original Sin. I click buttons in other applications using the right button with my left hand, but I have to use the Left button to click buttons in Divinity. When in-game, even though the right button is configured as my primary button and works that way in all other applications, I have to click the left button to move my characters around.
