IE6: Hover stops working on AJAX page

sigilaea · March 17th, 2008, 09:58 AM

I have an AJAX page with a CSS menu at the top. My problem is the hover functionality stops working after someone clicks on one of the details in the main blue section. This only occurs in IE6. IE7 and FF work correctly.

The URL to the page is:
http://www.coralap.com/dies281css.aspx

Steps to reproduce:
1. Mouse over the top menu and verify the hover works.
2. Click on the circle with the number "1" in it.
3. Mouse over the top menu again. The items no longer light up and the "Products" flyout no longer appears.

I use a JavaScript routine to add an event handler for IE6, so that hover works. A also use VB code-behind for the download functionality.

I will post the CSS, VB code, HTML and the JavaScript below.

The code in "capcss.css" is:
body
{ background-image:url(images/capback.jpg);}

#caplogo
{ margin:32px 0px 10px 10px;}
