Several parties recently reported problems computing local / in-vacuo electrostatic potentials in PyMOL 0.99rev9. The fix was trivial, so I've pushed out a 0.99rev10 release.  If you haven't upgraded to 0.99rev9 yet, just skip forward to 0.99rev10. 
As usual, Mac/Win/Linux binaries for subscribers at and open-sourcers grab SVN branch b099 revision 2974.
