Thanks for sending those through to me. I've had a quick look over them and can see that it is in fact the stopping of the audio recording that is causing the crash. I'll have a good look over them/MixEmergency on Monday (it's Saturday here at the moment) and send you an e-mail once I find out more. In the meantime, can you let me know a little more about your system and how you are recording? (i.e. OS, Mac computer type, are you using your Mac's line-in or an external audio interface, etc)
