'debug' is undefined with Microsoft AJAX release and TextChangedBehavior.js

As with my previous post, we upgraded the AJAX framework on the weekend which broke a few things, but one control in particular that broke was our TextChangedTextBox which is based on Pete Kellner's timed postback control. Since updating we were receiving a "'debug' is undefined" error on line 1409 (which was in one of the JavaScript include files).

Having had this issue before I updated the TextChangedBehavior.js but that didn't sort it, I have the latest version of the Futures on the server too so I was lost. Turns out I had an old version of the AJAX Futures DLL within the Bin folder of the project.

So as with my post on the ASP.Net forums before -make sure you update your AJAX Futures when updating your Microsoft AJAX framework!
