BTW, I'm running Audition CC 2014, 2014.0.1 release build 7.0.1.5 (64-bit) here:
Well, 2 things seem to have stopped my crashing. First, is I unplugged my Korg NanoKontrol2 and disabled remote service in Audition settings. Then second, Adobe released a patch for 2014 early August (a "fixit" patch) (see my current version above). Since then, no more crashing or hangs. Also, my crashing/hangs always seemed to happen when I was entering commands too quickly it seemed, like Space, S, Space in quick succession. And I mainly crashed/hung in Multitrack mode more often than editor mode. And yes, it seems there is definately a relation to window focus. If I was in Multitrack, and got a pop up notification from Chrome about an email, and I followed the notification and came back - BOOM - crash.
Although I unplugged the Korg, I continue to use the Logitech G13 without issue (knock on wood).
