change <option> stylebackground
<p>Why would this not work. This is referring to the option tag in a select tag.
If I remove the mouseOut style the mousOver works.</p>

<pre><code>//inside a loop    
option[b].onmouseover = Custom.mouseOver;
    option[b].onmouseout = Custom.mouseOut;


mouseOver: function() {
    this.style.backgroundColor = "#999999";
}
mouseOut: function() {

    this.style.backgroundColor = "#e8eff4";

}
</code></pre>
