Enlisting the help of jQuery, this is relatively simple to do. You'd first add a reference to jQuery in the HEAD section of your page:
Code:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="ajaxtabs/ajaxtabs.css" />
<script type="text/javascript" src="ajaxtabs/ajaxtabs.js">
/***********************************************

***********************************************/
</script>
Then, use the below modified .js file. To modify the fade duration, try finding the two instances of fade() inside the file, and pass a number to both of them in terms of milliseconds, such as fade(1000).
