Relative paths are always interpreted by the applet as relative to the we=

page in which the applet resides.

I believe it should work if you use a URL that specifies the 'file://'
protocol

On Windows

  file://c:/molecules/something.xyz

On *nix
  file:///home/angel/moleculas/algo.xyz

Using the signed applet, you should be able to load compressed files
directly from the PDB using the following cgi:

load
=22http://www.rcsb.org/pdb/cgi/export.cgi/1CRN.pdb.gz?format=3DPDB&pdbId=3D=
1CRN&compression=3Dgz=22;


(As a reminder, you must use the *signed* applet if you wish to allow the=

applet to contact web servers other than the web server from which it was=

loaded.)

It has been some time since I tested this, but I believe that it should
still work.
