I just reviewed the questions log from the webcast. It appears that some of the questions that were in the Q&A manager disappeared before I was able to view them. I want to sincerely apologize if you felt that I ignored your question. I did not. I always do my best to answer every last question to the best of my ability. In my opinion, getting your questions answered is the greatest benefit of attending a live event instead of just watching a recording. As a mea culpa, I have gone through the questions and posted my best answers.

Q: Are AJAX Control Toolkit controls production-quality
A: My opinion is yes. Every release of the AJAX Control Toolkit goes through rigorous testing. As with any software, bugs are possible. All known issues are available for viewing at http://www.codeplex.com/AtlasControlToolkit/WorkItem/List.aspx.
These are the only questions I don't remember answering. Please let me know if I missed any.
