[jQuery] css background-color not exists in IE with more then 2 classes..

[Mech7]

Does anybody know why in IE:

jQuery.css(e, "background-color");jQuery.css(e, "background-color");

Not works on a elementl like:

<div class="directions rounded-big">
</div>

But will work with..

<div id="directions" class="rounded-big">
</div>
