Object Required - ScriptResource.axd

 I am stuck, big time. I am trying to use the AJAX Control Toolkit.

I am using Visual Studio 2005 and I am creating an ASP.NET 2.0 web application. This application is using  ASP.NET AJAX version: 1.0.61025.0. This part is working correctly. I have successfully created an UpdatePanel to verify it. However, whenever I try to use the AJAX Control Toolkit, I receive a JavaScript error that states:

Message: Object required
Line: 87
Char: 9
Code: 0
URI: http://localhost:2379/myApplication/ScriptResource.axd?d=oyNxO7LFtj-jAU1vdv1uRHpgLIQtrDOvelwgkrlF1LW_jceo5_8XoQjwL-pjPJLMtTvDDa2JGWSdj1_IaEV6Cjim22TR8f0nC2VD3R3j9ak1&t=633718469659762256

The only thing I have done is use the ModalPopupExtender, which I have had success with in the past.  I am using version 1.0.10618.0 of the AJAX Control toolkit. I have copied the web.config file from the AJAXControlToolkit Sample Website. I am very confused at this point. What is the cause of this problem and how do I fix it?

Thank you!
