Ajax Control Toolkit not working in IIS8

Hi,

I'm using Amazon AWS EC2, running Windows Server 2012 and IIS8, for our new company website. Ajax Extension like Update panel works perfectly, but the AJAX Control Toolkit controls like DropDownPanel and Accordion I'm using doesn't seem to work at all. Refer to this link if you want to replicate this problem: http://ajaxcontroltoolkit.codeplex.com/workitem/27358

Don't know if there is a solution yet, but this is very frustrating.

Regards,

Quentin
