I have a problem with loading pse (session files) in a different computer than the one where the pse was created. I cannot see most of the structure,--it appears as if there is too much light...I'm copying the view from Pymol. Any idea why this happens? How can I fix it?

I've seen many complains about pse files (e.g. takes up a lot of memory), but I need to use them a lot just for graphical purposes. For example, if I save a Pymol session with a beautiful view for a publication figure, next time if I need to change a label etc., I can simply load the session and modify it. But is there an alternate way to do this, probably by using scripts?
