This is a situation that probably doesn't apply to anyone besides me.
Our squadron uses a Teamspeak server as well as in game voice.
So I use the same key to transmit on TS and channel game voice.
AH will crash if I press my transmit button before I am completely in an arena. This crash causes AH to stop responding and I must use Task manager to kill it . Once in an arena it works fine.
I use T at the moment but have used others as well to no avail.
I think using LCTRL would resolve the issue but AH won't let me map a CTRL key alone for the voice transmit function.
