Hi, I have a problem with my Razer Mamba TE. The Mousebutton 5 : http://puu.sh/rPzLt/d1c0e1c4dd.jpg (11) does not work from time to time... Sometimes its working fine but mostly it doesnt work for few weeks... I dont change anything on my computer in these week to be honest... the other mousebutton (10) works fine everyday... I already reinstalled Razer Synapse and also deleted the driver and restarted my computer. Do you guys think its a software problem or is the mouse just broken somehow?
