[PyMOL] Workaround for Crash on MacPyMOL Startup

[Warren D. <wa...@de...>]

MacPyMOL Users,

We have figured out why MacPyMOL was crashing for a select subset of =
users on start-up.  It only happens if you extract our ".tar.gz" archive =
using StuffIt Extractor instead of Mac OS X's built-in extraction.  The =
ultimate cause is rather esoteric: I had inadvertently enabled the Hide =
File Extension attribute on the splash screen PNG file, and StuffIt =
Expandor seems to have a serious bug extracting such files.

MacPyMOL should just work if you use Safari's default ".tar.gz" handling =
when downloading from http://delsci.com/beta.  With Firefox, you need to =
make sure that StuffIt Expander is not used for ".tar.gz" files.

If all else fails, simply pop up a terminal and resort to:

tar -zxvf macpymol-0_99beta29.tar.gz

Cheers,
Warren

use of his laptop for a few hours to help us to figure this all out. =20
