SendAndLoad Problem running locally but through html page

Hi

I have a flash application that uses sendAndLoad to load in some data from xml. This works fine when i run them locally through the Flash Player, however still running locally but inside a html page it doesnt work at all.
For some reason the xml onLoad returned result is just blank.

Anyone any idea why running it locally inside a html file would stop it working? I dont see how it could be a crossdomain thing, as i am running it locally so it isnt on a domain.

Any help?

Thanks
