This is my case:
Several months ago, I started to suffer this annoying issue:
while in play, I heard the "plug/unplug" sound from windows, and I suddenly lose control from anything related to the mouse (torso twist/yaw, firing weapons, etc...). In fact, my mech keps firing as if I were still pressing and holding the same buttons since the issue started (sorry, no english speaker, don't know if this is easy to understand): it means a lot of ammo and heat, so usually I get overheated and killed before I manage to do anything. (IN FACT, some times, after I plug/unplug the mouse to recover the use of it, my mech starts to fire as it is deployed in the map).
After so many times, I have a kind of accurate idea of what "triggers" the issue, but there is no way to avoid it, apparently.
-machine-guns, rotatory auto cannons, ultra auto cannons... any "suppresion gun" that requires press and hold any button in my mouse triggers the issue (I have tried to bind the MG/RAC/UAC weapon group to a different button, and it didn't solve anything).
How do I do to "handle" with it? I use the SCAPE button to get in the "quit match" menú. This stops firing. Then, I plug/unplug the mouse (thanks heaven, I got an USB switch in my PC's front) and, if I'm lucky enough, I can end the match alive. But it doesn't avoid anything. At any time in a fight, just for an unknown reason, it will happen again.
I have asked to MWO Technical service, by the way, and still no solution at sight.
