I apologize in advance if this rehashes some of the material in a recent post, but I'm seeing two "types" of render hang discussed for long-form renders in Vegas 6. In mine, I'm not getting an error message. The render just goes for about 45 minutes (on a nested timeline) and then--stops. Sits on one frame (different frames in two tries) and I have to hit cancel on the progress bar window, then close Vegas, etc.

Is this likely a CPU overheating? I have Dynamic RAM set to 0 because that's necessary to get a full-version Boris FX plugin to work. BTW, this did not happen when I rendered a good two-hour project from Vegas 5d.
