Hi, I have recently bought the new A4Tech X7 XL755BK Gaming mouse , it is really good and comfortable, but the reason i really bought this mouse is bec. it has 8 buttons, the left and right , the middle, and a 5 thumb button, but i have a problem in games, when i want to change the controls , like changing the voice chat to be mouse button 6, it dosent work, the buttons that work in the mouse are: mouse button 1,2,3,4,5, but 6 and 7 and 8 are not working, when i press it, it doesn't work , is there a solution for that? i tried to download the drivers, but it didnt help, should i delete the old driver before downloading the new one? is it possible that the game does not support 8 mouse buttons? is there something wrong with the mouse? please help me !!!!
