i have been trying to get a JavaScript tool tip pop up working correctly, the pop up works fine except the position doesnt work properly in IE8

in firefox the position is correct and remains correct even if the window is scrolled.

however in IE8 the position is correct if the window isnt scrolled but if the window is scrolled then the tooltip moves away from it anchor point up the screen equal distance of the amount the window is scrolled down.

you can see this in action here by mousing over the link "Go Direct To Dating Direct"
http://www.online-dating-reviews.co.uk/index.asp?page=retailer_details&option=shopping&p3=12861

the main code is below

the link triger code is:
<a href="thispage.html" onmouseover="doTooltip(event,0)" onmouseout="hideTip()">text</a>

postional display div is as follows, and is placed just before the end body tag:
<div id="tipDiv" style="position:absolute; visibility:hidden; z-index:100"></div>

can anybody please help with the possitional correction for IE8

thank you

Can I suggest you use newer script?

The main support for browsers in this script is Netscape.

So I suggest you upgrade to a modern script

for example jQuery or walterzorn's

The following works on every browser I have tried it on --

<A href="" target="_blank" onmouseover="self.status='Make a New Page';return true" onmouseout="self.status='';return true"><IMG src="new.gif" title="Make a New Page" width="27" height="12" border="0"></A>

Give it a try!  Adjusting the link and target of course.

self.status ????

Must be a synonym for title

1. self is not obvious - could be window, this would be more obvious
2. status is not a valid attribute for anchor according to w3org
3. why use javascript when you can just use title="Make a new page" ???

4. This said it does work in Fx, Safari and Chrome on Mac but I have NEVER seen it before.
