At first, I thought my mouse is broken. But I find it works perfectly when I tried it on web page. So I wonder is it some kind of bug and is there anyone else has the same issue with me? Lost couple game because of this, kind of frustrated.
There was a short period of time where my Rat 7 middle mouse button would not work. I rebound camera movement to wasd anyway, and it works better. The mouse works now, pretty weird.
I have this issue if i use my laptop with a usb mouse. For some reason middle button on the mouse doesn't seem to react in game but using the muti-touch gestures on the laptop's touchpad works.
