I'm getting a Javascript error "Sys is not defined" when I use the RadAjaxManager to monitor a RadTextBox. If I change the textbox to a normal ASP textbox, things work fine. My app is configured the way your troubleshooting FAQ suggests, and I'm still getting the error. I've also noticed that I get the same problem when I use a DES (Peter Blum) textbox. Any ideas?

Check if your website is "AJAX enabled". If you are sure it is - create new blank AJAX enabled website and copy the web.config into your current site.

The site is AJAX enabled. As I stated earlier, everything is configured the way you suggest in your troubleshooting FAQ. Also, everything works fine with a plain asp:textbox, but breaks any time I use an "enhanced" textbox such as Peter Blum's textbox, or one of Telerik's textboxes.

Turns out it was a problem with an associated image button not being wired up to the manager. Removing the button, or wiring the button up fixes the problem.
