IE error c.get_request()._get_eventHandlerList()._list.completed.reverse();

[Ravi]

Hi,

I am new to telerik controls.  We are using  RadControls for ASP.net AJAX Q2 2009.
In one of the page, I am poppingup a window using a ModalPopupExtender.
The modalpopup window  has buttons which postsback. Since I don;t want to post pack the whole page, 
I decided to put it within the updatepanel.  Now It starts giving me error in IE.  But it works fine with Firefox.
The error I get is in Telerik   js.
c.get_request()._get_eventHandlerList()._list.completed.reverse();

Does anyone know how to fix this issue.

By the way I am using VS 2008 3.5,    AjaxControlToolKit 3.5

Thanks
Ravi
