Well this was embarrassing today on Pilots Edge of which I fly regularly as well as with FS2 Crew PMDG NGXu. First voice did not work, so instead of dumping my flight, I switched to button, That was nice, except it locked in a routine which just stuck on one checklist item and repeated and repeated. Well, I tried to switch back to voice, no luck. Just plain stuck in repeated check list, again and again, So I looked for a way to just dump FS2 and NO Way . . .
This doesn't happen often but there has got to be a way to close a program if it locks. . . . just frustrated and disappointed. . .
