Loading random SWF's and IE 7 issues

programming flash

Hi all

I am using this code to load in a bunch of random swf files onto my stage to create a sort of star field effect, but with words instead of dots and it doesnt work in IE 7. Can anybody explain why, or recommend a better solution. It works in all other browsers IE 6 Safari 2 and 3 Firefox Opera etc. I am using a Mac btw so i can only tell from what people are telling me.

you can see it in action here http://www.gregrochford.co.uk/charles

var mc = this.createEmptyMovieClip("mc", 1);
function nextRandom() {
    var swf = this._url.substr(0, this._url.lastIndexOf("/")+1)+"swf/image"+Math.floor(Math.random()*26)+".swf";
    mc.loadMovie(swf);
}
nextRandom();
this.onEnterFrame = function() {
    if (mc._currentframe>=mc._totalframes) {
        nextRandom();
    }
};

on a side note, does anybody know the code to remove the “mc” from the stage when the user goes back to the beginning? i thought it was this

mc.clear();

but that doesnt work.

Many thanks

Greg
