I'm not sure if it's a key doing that, as I've switched my Afterburner and Flares key, and it still happens. And it doesn't happen as a normal crash where I get the game 'stopped working' message. I've never had this problem happening before.
It's interesting because the 3 times it happened I was doing the same thing, dropping bombs, using the afterburner, popping flares and turning or climbing by the centre of the Test Airfield map. If anyone knows what can be causing this and care to help, I'd be very thankful.
