I've updated to the latest version of the AjaxControlToolkit, but it still doesn't seem to work. UpdatePanel for example works the first time, but it never hits my endrequesthandler.
I have experienced a similar problem. I have replaced scriptManager elements in the page with ToolKitScriptManager and it got working. ToolkitScriptManager can be found in ajax dll. If you havent imported ajax dll upto now there is a step by step explanation here http://dotnetguts.blogspot.com/2008/06/ajax-control-toolkit-vsnet-2008.html
Hope it helps
