Again before I get from Nineline give us the logs, no Crash logs were generated, eg DCS didn't catch that it had an exception it just closed to desktop and the only thing in the log file was the standard items about ED CORE: having recently updated the map size when i last zoomed.

Stable is fine just the Open Beta doing it.
