QUESTION: Does 7.2 update fix createEmptyMovieClip issues?

[Lightwave Network]

Hello fellow Flash junkies,

Recently found out that createEmptyMovieClip doesn't allow the onLoad event handler, (read something about it being corrupt.) My question is does the latest 7.2 update fix this issue, and will the following example work?

_root.createEmptyMovieClip("myMovie", 1)
_root.myMovie.loadMovie("myfile.swf")
_root.myMovie.onLoad = function() {
  this._width = 500
  //etc.
} 

Thanks much!
