Graphic is Misaligned in IE7

I have a javascript slider that is misaligned in IE7 but works great in IE8 and all other browsers. The site can be viewed at http://www.learningconnectionsweb.com/. I would love any feedback into what might be going on. The CSS code for that area is
#DDSlider {
height:425px;
width:899px;
position:absolute;
top:0px;
display:block;
float: left;
}

Have a try adding text-align:left to that css.

That did the trick. Thanks much.
