idleMonitor in IE8

[saprobionte]

Hi, I found a weird behaviour, and I'm asking what's wrong. I got a page with :

Code: Select all

 <p:idleMonitor timeout="300000" >
         <p:ajax oncomplete="window.location.reload()" event="idle"/> 
</p:idleMonitor>

(if user idles for 300s, I refresh current page).

This code works well, page is refresh correctly. Now, I have a css containing :

Code: Select all

 body {
	margin: 0;
	padding: 0;
	line-height: 1.5em;
	font-family: Verdana, Arial, san-serif;
	font-size: 12px;
	color: #e7eaeb;
	background: #6d6a6b url(images/templatemo_bg.jpg) repeat;
}

In IE8, I start my website, and when I refresh the page, I got an error message : "This tab has been recovered". If I comment out the idleMonitor, I no longer have the error. If I comment out the "background" line in my body css, I no longer have the error. I just can't see the link between the two. How could I bypass that ?
