The width of the tooltip can be changed as you've mentioned. Below you can find an example for the same in which I've used a width of 1000px for the tooltip with a very lengthy tooltip message.
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Untitled Document</title>
<style type="text/css">
#dhtmltooltip {
position: absolute;
left: -300px;
width: 1000px;
border: 1px solid black;
padding: 2px;
background-color: lightyellow;
visibility: hidden;
z-index: 100;
/*Remove below line to remove shadow. Below line should always appear last within this CSS*/
filter: progid: DXImageTransform.Microsoft.Shadow(color=gray,direction=135);
}
#dhtmlpointer {
position: absolute;
left: -300px;
z-index: 101;
visibility: hidden;
}
</style>

The site you've mentioned in your post seems to be not online at the moment. To view the above code correctly save the tooltip image from the script page in the same folder of the above code.
I've checked the above code in the following browsers:
MSIE 5.5
MSIE 6
MSIE 7
Mozilla Firefox 2.0.0.15
