I can't stress enough how important it is to save before and after any changes are made to a scene. I wish Poser had the ability to undo more than the last task. That's why I started saving between additions, but it's saved me many timees when Poser has done something weird and I was able to pick up where I left off thanks to a prior saved .pzz file.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
