iframe load event

[Steve Onnis]

I am creating an iframe on the fly

var myIFrame = new IFrame({

        src: "bla.html",
        id : "myframe",
        styles: {
        width: 0,
        height: 0,
        border: "none",
                visibility : "hidden",
                display : "none"
        },

    events: {
        load: function(){
           alert("iframe loaded");
        }

    }

.... but in IE the load event does not seem to get triggered.  In all
the other browsers i have tested it in it triggers but not in IE.
Anyone else come across this?
