That's why I think I did something not quite right in the process. I stopped rendering using the "Stop" button, but did'nt hit any of the "display preferances". When I saved it to a different name, it still came back up rendering. Perhaps the on and off of the display preferances turned off the CUSTOMRENDER setting. It's a great find. I've had it hang up rendering several times, and (with a red face) had not saved the settings! Thanks.
