[jQuery] jquery.corners not Working in Mac FireFox 2 or Windows IE 7? Demo Page Provided


I have a page where jquery.corners works perfectly in Mac Safari, Mac
Firefox 3, and Windows Firefox 3, but not in Mac Firefox 2, or in
Windows IE 7. How can I correct this? An online demo is at this link:

Thanks very much in advance to all for any info.
