Inheritance Object method in IE
<p>I've defined method fadeIn for Object</p>

<pre><code>
Object.prototype.fadeIn = function(d, callback) { //some code here };

....

var b = documentGetElementById('b1'); // &lt;div id="b1"&gt;&lt;/div&gt;
b.fadeIn();
</code></pre>

<p>It works in FF, Opera, Chrome, but IE reports "Object doesn't support this property or method" when I try launch fadeIn. Why IE doesn't inherit my methods from Object and how to fix it?</p>
