Alright, I started a new topic for this one. Hopefully it hasn't been mentioned. When exporting a video, I notice when it gets close to 100% and stalls (which I have mentioned before), I figured out a work around until this issue gets resolved. While it's in stall mode - I click the Apple sign in the menu bar and choose "Force Quit", as soon as I do that the MixEmergency exporting gets going again. I have to this for every pass until it is done. Is it annoying? A little. BUT, at least I can get my exports out ... which is a good thing :)
