Flew LB2 for hours tonight with no problems ( except for two times when the blue Windows clock in the task bar was visible in the cockpit lol ). The difference? I wasn't using the X-45 stick, I was using my ancient Gravis Gamepad ( I'm not sure how old it is but it has hieroglyphics on it lol ), then I uninstalled the SST, re-installed it and switched to my X-45 WITHOUT using the profile I made for it. Stick rudder and throttle worked but was using the keyboard for most other functions, again hours of blissful helo flight.
Later I will load a copy of the profile and see what happens, if it still CTDs I will rebuild it manually. I have a sneaky suspicion it will have to do with a repeat rate on one or more buttons, or it may have simply gotten corrupted somehow.
