Problem Mouse bug

Hello,
I encounter many problems with the menus of the game.
When assigning key double click automatically assigns the mouse button, you can not make another choice.
Sometimes it makes impossible to get to the bottom of the screen.

Have you an idea of the origin of my problem?

Driver and Firmware updates mouse and keyboard.

Thanks for helping

 

don't click just press escape if you don't want to assign a button too the option.
