Several times now with the latest update I've had the video playback freeze during editing and I have to close out. When I go back in ALL THE EDITS I'VE DONE ARE GONE in spite of the fact that I was saving frequently during the edit. This has happened 3 times since the latest update of less than a week ago. Each time this happens I can lose an hour of work even though I've done frequent saves all along. This update is 100% garbage!
