Dear all,
I am trying to use PyMol plugins but I have some problems.
In the reported case the Caver plugin was considered (following usage notes reported in, for your information similar problems were encountered with builtin PyMol plugins (e.g PDB Loader). I think theres something wrong with my configuration/environment variables, can you give me some hints?

PyMol version is 0.99 beta 33 (binary) on Windows XP Pro sp2.

Thank you in advance for your help.
