I don't know that I'd classify this as a bug. It happened in earlier versions too. When the controller hands you off and the FO dials in the next frequency, if you attempt to respond before he dials in the new frequency, you get an unhandled exception. It's really just a matter of waiting 2 or 3 seconds before responding. Just a heads up for those that may have encountered the same issue.

Mike,

Thanks for the report.  I'll see if I can stop the exception.
