Envjs envjs

Hi,
I’m new to javascript and also envjs. I use Rhino as script engine under Windows XP.
My test script is very simple:
load (libs_path + 'json2.js');
load (libs_path + 'env.rhino.1.2.13.js');
Envjs.scriptTypes['text/javascript'] = true;
window.location = 'http://localhost:8080/';

console.log ("Done..");
I got into problem when executing
window.location = 'http://localhost:8080/';

Seems that there is issue dealing with file path under XP when it tries to create a simple file for cookies. Is there a way around this??
