Chrome - underlining certain links?

Question

I'm updating some style sheets that were working perfectly in FF and IE, but are broken in Chrome, and some links (not all) are being underlined. I cannot for the life of me see where in the CSS or why. It's driving me nuts. Any suggestions?

Edit: this is some of what is turning up in Chrome's 'matched rules' section, if that helps..

div#contentPanel a:hover, div#rightSidePanel a:hover {
border-bottom: 1px solid #1D7E98;
text-decoration: none;
}
div#contentPanel a:link, div#rightSidePanel a:link, div#contentPanel a:visited,      div#rightSidePanel a:visited {
border-bottom: 1px dotted #AAA;
}
a:hover {
color: #1D7E98;
text-decoration: underline;
}
a:link {
color: #18C1E8;
}
a {
text-decoration: none;
}
