For the last couple weeks, when rendering my edits through Vegas Pro 12, it will just stop. The elapsed time keeps going, but the frame number and % done completely stops. Then when I cancel the render, it does nothing. I ultimately have to go to Task Manager and manually stop Vegas. I also noticed that when this happens, it drops dramatically from 60 - 80% CPU Usage down to 2 - 4%. This happens 4/5 times now and is getting extremely frustrating. Anyone ever hear of this happening before?
