NEW ZOOM BUG
Audition can't adjust correctly the new zoom (to see all clips) view into multitrack panel when there's more than 200 tracks.
Can you elaborate further? What do you see right now, and what do you expect to see? There is a maximum number of tracks that can be displayed at a time, even at their smallest track height, so depending on track count and monitor resolution, you may still need to scroll down to see all tracks.
