Hello! i had discovered b4&5 dont work, i have "drop" as "button 4". also, "button 5" wont work because I set that to crouch. If you look into this, thank you so much! this drastacly lowers my skill in server pvp which is an ouch.

i cannot put a screen shot but i will explain the scenario.

On the side of the mouse, there are two tab buttons known as button 4 and 5.

 

i go to bind them, but nothing happens when i press it. I know my buttons arent messed up because i used it on a computer and it worked good.
