Icon reloading issue

I'm having a serious issue in IE6, my page is continually loading some icons set on li elements.

Two examples of which are:

span.entry-category {
background: url('images/famfamfam-mini/page.gif') no-repeat;
background-position: 0% 50%;
padding-left:20px;
}

and

div#rightcolumn .affiliate-links li {
margin-left:0px;
background: url('images/famfamfam-mini/icon_favourites.gif') no-repeat;
background-position: 0% 50%;
padding-left:20px;
}

Works fine in IE7 and FF2, IE6 just reloads these images all the time. It's basically a list-style-image but applied like that so it positions correctly. Any ideas?

Cheers

Disregard, this was an IE6 issue with JavaScript
