Audition crash when save

If you get crashes and you want to know why, you need to follow the information in this thread (or alternately look for the crash reports when Audition is actually open by using the Help menu option) and post the text of the log file(s) into this thread. We can spot the obvious, but not necessarily everything. Anyway, that's the way to start to find out what the issue is. Also, where are you trying to save these sessions to? A local disk, or something cloud-based? The latter will almost inevitably fail...
