IE 7.0 Only problem with visited tags

At http://theatomicconservative.typepad.com/ when I click on any of my links the text at Subscribe to this blog's feed turns red (which is the color is should change to when clicked. I've verified the issue is whin the visited css because when I change it to green it still changes to green.

Thanks for any help you can give me

/*.module a:visited { color: #d22539; }*/

.module a:hover { color: #1e77f5; }
.module a:active { color: #1e77f5; }
