Header Image Opacity Panels Not Appearing in IE7
 

Apologies if this has been asked and answered, but I did look...

I can't figure out why I can't get the right and left opacity panels to show up in IE7. The central portion of the image is flanked by two white boxes.

I have adjusted the opacity settings, and it looks right in Firefox - but no dice in IE.

Suggestions?

Many Thanks,
Laura
