Jeez, why are you making so many problems? Devs would make a new Choose Weapon Window and everything would be fine... Look! Yellow and green buttons are viewable at the same startup. If someone choose PW (Primary Weapon) in yellow area, game will show him buttons in red area! Then, player can choose between second PW or SW (Secondary Weapon). If he choose PW, the buttons in green area will be hidden! Analogic situation will happen for SW...!
