Lytebox in Iframe with IE

[reversed]

Lytebox should enlarge an image when you click on the thumbnail.

if you want to see how it works or where i downloaded it:
http://www.dolem.com/lytebox/

so now i have it working on google Chrome. in the iframe page i have this code: <script type="text/javascript" language="javascript" src="lytebox.js"></script>

and in the parent page i have a link to the stylesheet:
<link rel="stylesheet" href="http://pcavereest.nl/lightbox/lytebox.css" type="text/css" media="screen" />

but my problem is: i click on the thumbnail in IE and then it enlage's inside the iframe and it has no effect at all. the image just appears. when i go to the page itself (the iframe page not the parent) it works fine.
i just want that when i click on a thumbnail it enlarges outside the iframe.

And i noticed an error on the left-bottom of the screen. it says: access denied, at rule 651 there should be an error?
can anyone help me with this error?

hope you can help me with this.
(sorry for my bad english)

[whatever]

Did anyone find a solution to this issue?

It has only started happening to my site in the last few days. I recently had my server upgraded from PHP4 to PHP5 so that is the only change on the system.

The lytebox does not pop up anymore in any browser but the following error appears in IE.
