So, I use one of my side mouse buttons to crouch. After a small update today, they stopped working. It was to the point were none of the buttons on my mouse would work untill I pulled up a new program, but now my side buttons didnt work in...

Just your agent's fist. Nothing else. Two fists would also be cool. Maybe boxing gloves? Left click would be a slap and the right click would be a right hook that swings across your screen. Also a plus could be a spiked glove of some sort....
