Pop up window position

[florida]

How can I make a mouseover pop up for a link where it pops up in the same exact position every time? I want to put links in this small pop up(on mouseover only) where the pop up comes up exactly in the left corner of my page everytime. On mouseout the popup window should dissapear.

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

leftPos = 0
if (screen) {
leftPos = screen.width-255;
}
topPos = 0
if (screen) {
topPos = screen.height-255;
}

newWin = window.open("","newWin","width=whatever,height=whatever,left=" + leftPos + ", top=" + topPos");

</script>

I think that will do it.
