div visibility onmouseover - Firefox issue

[marynorn]

I have a large image, which is divided into a lot of little maps. I've set a javascript behaviour which makes various div boxes visible on mouseover and hidden on mouseout. And it works perfectly... on everything except Firefox.

Why? I'm not used to Firefox doing this to me.

Image:

<img src="images/3d_home.jpg" width="500" height="337" border="0" usemap="#demo3" />

<map name="demo3" id="demo3">

 <area shape="poly" coords="319,139,297,162,367,194,383,162" onmouseover='document.getElementById("info1").style.visibility="visible";' onmouseout='document.getElementById("info1").style.visibility="hidden";' />

 <area shape="poly" coords="391,163,368,205,451,239,463,193" onmouseover='document.getElementById("info2").style.visibility="visible";' onmouseout='document.getElementById("info2").style.visibility="hidden";' />

 <area shape="poly" coords="382,214,356,220,364,237,376,235" onmouseover='document.getElementById("info1").style.visibility="visible";' onmouseout='document.getElementById("info1").style.visibility="hidden";' />

 <area shape="poly" coords="240,162,235,184,241,202,249,181" onmouseover='document.getElementById("info4").style.visibility="visible";' onmouseout='document.getElementById("info4").style.visibility="hidden";' />

 blah blah blah, more of the same

</map>

div boxes:

<div id="info1"><p>Information box goes here</p></div>
<div id="info2"><p>Another information box goes here</p></div>

and so on...

stylesheet:

#info1 {visibility:hidden;}
#info2 {visibility:hidden;}

You get the idea.

I have a specific way I want this to look, and I've tried three different methods, all of which fail in one browser or another. I'm testing in eight different browsers, and I'm just about ready to go on a kill-crazy rampage.

Please tell me I've gone code-blind and there's a simple fix?

Works fine at my end. Please provide a link to the page in question.

I'm afraid I can't, it's still in the design phase, I don't even have a URL for the site yet. But the fact that it works for you suggests there's an issue with my Firefox settings.

Edit: Yep - a perfect example of why you should always clean off unused code as you stop needing it, even on early test pages. It was an old piece of code way down in the image map gumming up the works.

Thanks
