Sorry I didn't mention the operating system. It's WinXPpro. The computers are a Xeon 2.8GHz (1GB RAM, Nvidia Quadro4 900XGL) and a P4 1.4GHz (768MB RAM, Nvidia GeForce2 GTS). Both run pymol 0.89.
Now there is a twist to the story. We also run linux (redhat with 2.4.18 kernel) on a 2 CPU 930MHz (1GB RAM, Nvidia GeForce2 GTS) PIII. Working speed is much slower but no crashes when ray-tracing from the exact same pml script. The linux computer runs pymol 0.88. When I was using pymol 0.88 on either of the WinBoxes they were crashing just like now with pymol 0.89. Can it be that linux makes better use of its physical memory or that the 2GB of swap make the difference?
