Mine does the same thing i've kind of just dealt with it. i just hit it in multiples of 3 and spam [Confirmed] in gameI have quickchat assigned to "C" by default, but for some reason, every time I click F7 (which is supposed to lower the volume on my laptop), it activates the quickchat.
I've looked in the keybindings, nothing there is set to F7. What on earth is going on?
