IE's handling of <li>'s float:right; display:block; odd vertical spacing

[David Sudweeks]

Hi everyone. I've stumped everyone in the office with this one.

I've got a list. I want it to show up something like this, but with each li aligned right.

1 2 3 4 5 6 7 8 9
10 11 12 13 14 15 16 17 18

Here's the thing with borders drawn around it:

It displays perfectly in modern browsers, but IE renders extra vertical space between the first row and the second.
Like this:

1 2 3 4 5 6 7 8 9
[extra space]
10 11 12 13 14 15 16 17 18

and here's the html

<div id="blueprint">
	<div id=blueprintnavcase>
		<div id="holedetails">hole details<br />
			<div id=holedetailstoggle>
				SHOW / HIDE
			</div>
		</div>
		<ul>
		<li><a>9</a></li>
		<li><a>8</a></li>
		<li><a>7</a></li>
		<li><a>6</a></li>
		<li><a>5</a></li>
		<li><a>4</a></li>
		<li><a>3</a></li>
		<li><a>2</a></li>
		<li><a>1</a></li>
		<li><a>18</a></li>
		<li><a>17</a></li>
		<li><a>16</a></li>
		<li><a>15</a></li>
		<li><a>14</a></li>
		<li><a><span>13</span></a></li>
		<li><a>12</a></li>
		<li><a>11</a></li>
		<li><a>10</a></li>
		</ul>
	</div>
</div>

and the relevant css

#blueprint {
	width:1000px;
	height:950px;
	margin-left:auto;
	margin-right:auto;
	text-align:left;
	background:url(../images/design/blueprint_13.png) no-repeat top left;
}

#blueprintnavcase {
	margin:100px 10px 0 0;
	float:right;
	width:240px;
	text-align:center;
}
#holedetailstoggle {

	font-size:7pt;
	
}

#blueprintnavcase ul {
	padding-top: 38px;
}

#blueprintnavcase ul a:hover {
	color:#a9cbe8;					/* color: blueprint numbers _over_ */
}

#blueprintnavcase ul li {
list-style:none;
border: 1px dotted red;
	color:#7ea4c4;					/* color: blueprint numbers _up_ */
	float: right;
	width: 24px;
	height:25px;					/*  <----<<<   *********** THE IE CULPRIT (except not really) This one's got me stumped. #############*/
padding:0px;
margin:0px;
	text-align:right;
	display: block;
}
#blueprintnavcase ul li span{
	color:#e8eff4;					/* color: blueprint numbers _down_ */
}

The padding at the top of the UL is carried across when it wraps. I wrote these (highlighted) as IE proprietary, but they probably will work in all browsers if used in the stylesheet in place of the current ones that govern these property values:

<link href="styles/screen.css" rel="stylesheet" type="text/css">
<!--[if IE]>
<style type="text/css">
#blueprintnavcase ul {
padding: 0;
}
#holedetailstoggle {
padding-top:38px;
}
</style>
<![endif]-->

Perfect!
Much appreciated.
Merry Christmas.
