two site problems

[Computer Acolyte]

First one: imagemap problem.

Here's where: Link. On the upper right side you'll see a Steam/Valve image map, that's supposed to have two links. For some reason, when I open the link with IE, only the Steam link works, with Firefox everything's ok.
Here's my code:

<map id="valvemap" name="valvemap"
<area href="http://www.valvesoftware.com/" alt="Valve Software" title="Valve Software" shape=rect coords="0,51,130,115" />
<area href="http://steampowered.com/v/index.php" alt="Steam" title="Steam" shape=rect coords="0,0,130,51" />

......

<img src="valvelogo.JPG" border=0 usemap="#valvemap"/>

Second problem: Javascript.
Link. I'm trying to do pop ups, the links are the ones that say 'here', and can be located near the bottom.
When I open the page with Firefox or Opera it works, but IE gives me this:
Line: 8
Char: 1
Error: Invalid Argument
Code: 0

The script I use is in the head section:

<script type="text/javascript" language="JavaScript">

function PopUp(url) {
window.open(url,"John 5 extra info", 'scrollbars, width=750, height=500');
}

</script>

And I call the function like this:

<a href="javascript:PopUp('John5Info.html')">here</a>

Thanks in advance.
