Just FYI: This is an unfortunate unavoidable consequence of the fact that we use Python's portable, platform-independent "pickle" machinery for PyMOL session files. Packing or unpacking a Session or Scene file thus requires that there be two simultanous copies of the information to reside in RAM simultaneously: one native and a second in Python itself. So when memory is a limiting factor, we definitely recommend using scripts instead of sessions. > > > PyMOL simply crashes under Windows Vista Home Premium as well as under > > Ubuntu Linux v8.04 LTS without error report.

Correct -- To get those same console messages on Windows, you need to launch PyMOLWin.exe from a Windows command line with the "+2" option to prevent PyMOL from hiding the console window: (start menu -> run -> cmd [return]) cd c:\program files\delano scientific\pymol pymolwin + 2
