Hi David,

If you save a session file in the latest version of PyMOL there is never the expectation that prior versions can read that file. Such "forward compatibility" (of the older versions) is not supported. We do support, however, "backward compatibility" which is when newer versions of PyMOL read older session files.

Cheers,

-- Jason

I still have this problem:
session saved in 1.6 with a black background; opens in 1.5 (and earlier) with a red background

Many of my collaborators use old versions of pymol, frequently installed onto their machines when they were bought X years ago, and this essentially makes it so I cannot use pymol 1.6 as I cannot share sessions with them (at least not without getting weird e-mails asking why I have a sudden affinity for the color red).
