Finally! My problem with ongoing freezes in HTML source view (not to mention the designer) have been fixed. Rick has written about some of these issues here: http://www.west-wind.com/WebLog/posts/201463.aspx
See http://weblogs.asp.net/scottgu/archive/2008/02/08/vs-2008-web-development-hot-fix-roll-up-available.aspx for the hotfix and download details. Thanks to Scott Guthrie and his team. Bring on the MVC framework & VS2008 SP1!
