Left Handed Mouse setting not applied on startup. I use a Razer Death Adder left-handed mouse. On each startup, I have to go to Mouse Controls and set the button order to Right handed, then back to left handed, to click "Apply" for it to have effect. The ckeckbox remains set as "left Handed" on the next boot, but the mouse acts as right-handed until I do this trick on every login.
STEPS TO REPRODUCE
1. Set to "Left Handed"
2. Use mouse normally as left-handed
Mouse button order is that of a right-handed mouse.
Mouse button order should be of a left-handed mouse as per the settings.
