Any way to bypass this?
When/if Poser allocates more than 1.5 GB of memory, it enters what seems to be an infinite loop: No error message, no rendering (although it still uses 99% CPU). You know it has happend because the cursor is free (no hourglass), the screen refreshes faster than usual, and you can drag the render progress bar window freely around.

Using Process Explorer to check what Poser might be doing, I noticed that each time Poser had allocated 1.5 GB (and not an octet more) and gone sour... I've waited it out once, but after no single bucket was rendered in a whole week, I killed it.
It happens with different scenes on my 4GHz Athlon with 2 GB of (physical) RAM, but also on my old 3.2 GHz Athlon with (also) 2 GB RAM. Both are dedicated computers, nothing else is running on them. There shouldn't be any memory problem, since the total memory usage never goes over 1.6-1.7 GB, less than the available RAM, no need to swap (and my RAM is clean, both computers have passed 2 days of Memtest86 and 2 days of 95prime with no error). The suspicious thing is Poser always croaks at 1.5 GB, that can't be a coincidence.

And no, reinstalling a clean Windows (2000 or XP Pro) and Poser 6 (SR2) doesn't change anything either.

Any way to fix this? It's really a showstopper, especially for scenes which can't be cut in pieces (because of reflections and shadows).

Thanks in advance (even if I don't have much hope)... :-(
