i'm having an error in Telerik.Web.UI.Webressource line 1763 saying :
SCRIPT5007: Unable to get value of the property 'length': object is null or undefined

it is actually in the Telerik.Web.UI.Ajax.Ajax.js because I see /* START Telerik.Web.UI.Ajax.Ajax.js */ before the code that raise the exeption.
It seams to only appear in IE after a couple refresh of the page. The strange thing is that I don't use RadAdjaxManager or any Ajax controls in that page and the code seems to try finding update panel in my page.
UPDATE : forget it. I had a RadAjaxManager on a page without RadAjaxLoadingPanel and that is what was seems to cause the error
