I have a jQuery tools scroller set up with controls managing two separate divs of info - one images, the other related text that needs to sit over the top of the images with a transparent bg image. I am using z-indexing to achieve this and am aware of IE's issues with this but am unable to sort it (tested in IE6-8). Image of the issue below:

It seems that the overlayed div is taking on the containers white. Try as I might, I can't resolve this. HTML/CSS code below:

     <div id="content">

 <div id="nav"></div>

    <div class="s4 slideshow">
      <div>
            <img src="<?php bloginfo('stylesheet_directory'); ?>/images/hero_1_white.jpg" width="770" height="367" />
            </div>
            <div>
            <img src="<?php bloginfo('stylesheet_directory'); ?>/images/hero_1_white.jpg" width="770" height="367" />
            </div>
            <div>
            <img src="<?php bloginfo('stylesheet_directory'); ?>/images/hero_1_white.jpg" width="770" height="367" />
            </div>
        </div>

  <div id="overlay_bg"></div>

  <div class="s4 information">
      <div>
       <h1>Support</h1>
    <p>Quisque lacus quam, egestas ac tincidunt a, lacinia vel velit. Aenean facilisis nulla vitae.</p>
    <p><a href="#">Support Us</a></p>
            </div>
            <div>
             <h1>Events</h1>
    <p>Quisque lacegestas ac tincidunt a, lacinia vel velit. Aenean facilisis nulla vitae.</p>
    <p><a href="#">Read More</a></p>
            </div>
            <div>
       <h1>Regional</h1>
    <p>Quisque lacus quam, egestas ac tincidunt a, lacinia vel velit. Aenean facilisis nulla vitae.</p>
    <p><a href="#">Support Us</a></p>           
            </div>
        </div>

 </div> <!-- end of content -->

 }

Any help would be greatly appreciated.
