I have to agree with Bryster. I've had more than a hundred Bryce trees in one scene several times without crashing. In fact the last Bryce crash I had was before I ran the 5.1 update I've had big files that were slow to save and load and render but no crashes. And I've only got 512 ram. I'm afraid something more sinister may be at work on your machine attileus, like a virus, or a hardware problem.

This is not my "second childhood". I'm not finished with the first one yet.
