Editing a 3-hour video and every couple of minutes the program hangs indefinitely. Never fully crashes, it just hangs until I close it. I've tried pressing Esc to cancel an action or whatnot. Sometimes something as mundane as changing my place on the timeline triggers it. Very frustrating as I just upgraded this program for the second time, reluctantly, as I experienced issues like this early in Vegas 15's development. Anyone else experienced this issue? I don't have an error code or anything as the program never "crashes", it just stalls indefinitely.
