Are you trying to load an XML file from a host that is different than the
one you
loaded the app from? If so, that would be a browser security policy
violation, they
don't allow cross-site XMLHTTPRequest by default, although you can set the
security policy manually in the browser. This is a real deficiency of the
browsers, there is a proposal for a permissions file to go onto the servers,
much like the
Flash crossdomain.xml file, but I don't think any of the browsers have
implemented it yet, (except maybe Firefox?)

This occurs in both Flash and DHTML runtimes.  When I exported the test
