In Flash8 the XML.load("url") function will now
overwrite prior requests to the same XML Object.

Example:
PHP Code:
var myXML=new XML();
myXML.onLoad=chk;
function 
chk (suc:Boolean):Void {
    if(
suc){
        
trace("xml Loaded");
    }
}
myXML.load("testxml.xml");
myXML.load("testxml.xml");
myXML.load("testxml.xml"); 
Compiled for Flash7 it will trace "xml Loaded" three times;
compiled for Flash8 it will only trace it once!
