The webdevtools team has historically owned a control that shipped with IE5.5 and above. This control is the DHTML Editing Control. In order to improve security in IE7+, we took a hard look at this control and decided to remove it from Vista and IE7+. A post I made yesterday on the IE blog talks about this in detail. Please read it at http://blogs.msdn.com/ie/archive/2006/06/27/648850.aspx and let us know if you have any questions about this change. In particular I’d like to hear if you have an app that relies on this control and discuss your migration path with you.
