My least favorite button in games is when something is bound to the middle mouse button, it's always the first thing I rebind to one of the thumb buttons on my mouse because I always end up scrolling when I press it.  Even if I rebind nothing else, MMB gets rebound to something else no matter what it's used for in any game.   I couldn't see a binding in the settings for it. Does anyone know if there's an ini that I can edit to rebind it?

Thanks!
