Pete, It is a PyMOL fact of life that session files take more memory, because all state information must transient exist in both Python and C while the session is being loading. However, we should get that memory back after the session is fully loaded. If not, then you may be right about a memory leak. A good way to test this is to see what happens if you load the same session over and over again without restarting PyMOL. Does memory usage consistently increase or does it level off?
The most likely cause of this would be PyMOL failing to decrement the reference counts on certain session data. Cheers, Warren -- Warren L. DeLano, Ph.D. Principal Scientist .
