Your page is in violation of Dynamic Drive's usage terms (http://www.dynamicdrive.com/notice.htm), which, among other things, state that the script credit must appear in the source code of the page(s) using the script. Please reinstate the notice first.

That said, I'm surprised it ever worked. In IE it looks sort of OK sometimes. In the rest it's either at the top or below the image of the map. That's because browsers see the image as the trigger and position the tip in relation to either the top or bottom edge of the image taking into account the height of the image and the top and bottom edges of the page.

Use this reworked version of the script instead:

window.addEventListener("load", initalizetooltip, false)
else if (window.attachEvent)
window.attachEvent("onload", initalizetooltip)
else if (document.getElementById)
window.onload=initalizetooltip

Notes: It positions the tip relative to where the mouse is when it activates it and it allows the tip to remain if the mouse moves over the tip. Because of that I found I could shorten the disappeardelay and make other adjustments to the configuration.
