Hi !

In my XUL-Application I took your script calling a other 
XUL-Application. But I get a Errormessage !

Error: uncaught exception: Permission denied to get property 
UnnamedClass.classes

This error appears on the line :

var EventQClass = Components.classes['@mozilla.org/event-queue-service;1'];


Do you know the reason ?

Can you give me an advice ?
