category sidebox margin problems

[sonicparke]

I'm having a problem in IE with the last link in the category box. I added some padding to all the sideboxes and when I did that it looked great on all the sideboxes except the category box. The link in there balooned up exponentially it seemed. So I countered that with a negative bottom margin. That fixed it except in IE it cuts off the last link significantly.

Here's the code I added for sideboxes:

/*sidebox link formatting*/
.sideBoxContent ul li a:link, .sideBoxContent a:link {
	width: 143px;
	display: block;
	padding: .1em;
}

.sideBoxContent ul li a:visited, .sideBoxContent a:visited {
	width: 143px;
	display: block;
	padding: .1em;	
	color: #C0BFAB;
	text-decoration: none;
	border-bottom: 1px dotted;
	border-color: #FF0000; 
}

.sideBoxContent ul li a:hover {
	background-color: #b7d2d9; 
	text-decoration: none;
	display: block;
	width: 143px;
}

.sideBoxContent ul li a:visited:hover, .sideBoxContent a:visited:hover {
	background-color: #b7d2d9; 
	text-decoration: none;
	display: block;
	width: 143px;
	padding: .1em;	
	color: #FFF;
	border-bottom: 1px solid;
	border-color: #000;
}

/* Check on visited link */
	
.sideBoxContent ul li a:visited:after, .sideBoxContent a:visited:after {
    content: "\00A0\221A";
    color: #C0BFAB;
	}

.sideBoxContent ul li a:visited:hover:after, .sideBoxContent a:visited:hover:after {
    content: "\00A0\221A";
    color: #FFF;
	}

.category-top, .category-link {
	margin-bottom: -13px;
	clear: both;
	}

Can you see where I might have gone wrong?
