@Stewer: as long as the program communicates with Windows it's not out of memory yet, and the old (multi threaded) bucket rendering was apparently a neat process not using more than requested. The Windows message was an (negative) answer to the request.

The real thing happens when a program uses more than requested / allocated / granted. That's a "writing outside user area" error, triggered at the hardware level of your PC and fatal immediately for various good reasons. Recent OS versions, responding to that hardware trap, only kill the process instead of everything else too (the famous Blue Screen of Death).  
This apparently can happen during the (single threaded) Prepare to Render phase, when the memory usage goes two to fourfold.

But whatever, semantics.

Agree with the "can't find ..." remark, although Cyberdine is talking P7. But I can't remember having had that message at all, since Poser 1 that is.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
