--- Comment #8 from Dutch <d.puppybre...@gmail.com> --- The trigger appears to be that any audio track is locked. I had 2 audio tracks, both were locked. By unlocking both of them, the project file now closes as expected. Locking either audio track still reproduces the symptom. Locking video tracks do NOT trigger the problem. Yay, simple workaround. -- You are receiving this mail because: You are watching all bug changes.
