i created this simple prototype:

MovieClip.prototype._createEmptyMovieClip_ = MovieClip.prototype.createEmptyMovieClip;  
MovieClip.prototype.createEmptyMovieClip = function(n, d, ob) {  
var tempRef = this._createEmptyMovieClip_(n, d);  
if(arguments.length \> 2)  
for(var a in ob)  
tempRef[a] = ob[a];  
return tempRef;  
}

it works fine when i test the move normally, but gives me a 256 recursion error when i use the simulate download feature. Any idea why?
