[PyMOL] display problem (slab?)

[Marc V. <mv...@es...>]

Hi all

For some reason I am now having a strange problem when I use pymol
to display molecules.  It acts sort of like it is in slab mode where
some of the molecule fades into nothingness.  However, when I spin
the molecule, the same regions remain invisible.  If it were a true
slab effect, the regions that I spin into the slab would become visible
and the ones out would be invisible.  I wouldn't worry about it and would
just restart the program to eliminate the setting, but for some reason
it seems to now be a default and happens no matter what I do.  
I think I'm just missing something really silly, but I can't catch it.
Any ideas on how to restore normal function?


thanks,
Marc
