Unload .XML file

Hey all,

I have a flash file which loads 2 .xml files for 2 slideshows that sit on a page.

The problem is that if you click on another section of the site and then return the .xml file realods. If its loaded 2/3 times it seems ok but then if loaded 5+ times it confuses the interval/fadetime of the slideshow.

I have searched the forums for unloading .xml and not found anything appropriate. All I need to do (i guess) is unload the .xml file onRelease of any button on the navigation.

Any ideas on this? All input really apprecited as ever.
Thanks
H
