Rails spinoffs - May 2006 - IE DragDrop Oppacity Error

This is going to be tough to describe, so bear with me.

I am using the latest scriptaculous and prototype 1.5.rc0 

This error only happens in IE, FireFox handles everything just fine.

The error I get is: "Error: Object doesn''t support this
property"

Code Section that it breaks on (actual lines has comment at the end):

Effect.Opacity = Class.create();
Object.extend(Object.extend(Effect.Opacity.prototype, Effect.Base.prototype), {
  initialize: function(element) {
    this.element = $(element);
    // make this work on IE on elements without ''layout''
    if(/MSIE/.test(navigator.userAgent) && (!this.element.hasLayout))
      this.element.setStyle({zoom: 1});


    var options = Object.extend({                    //Break here on error
      from: this.element.getOpacity() || 0.0,
      to:   1.0
    }, arguments[1] || {});
    this.start(options);			    //Till here
  },
  update: function(position) {
    this.element.setOpacity(position);
  }
});


The situation:
	I created new draggable elements, upon clicking and dragging the first thing
that happens is the error specified. I know that it is happening in the
Effect.Opacity object because the item is made slightly translucent (default
behavior) on pickup. However, I don''t understand why it would break on
Object.extend as that is part of prototype and I don''t think it has
changed at all and it is only happening in IE and not FF (yes I did check the JS
error log).

I am confused, and thus going home. I''ll answer responses tomorrow
morning bright and early.
