All details links on your page http://expression.microsoft.com/en-us/library/cc296227.aspx redirect to the pages about "Expression Blend 2", not "Expression Blend 4".
The affected links have this strange suffix http://expression.microsoft.com/en-us/library/cc294537(Expression.40) that apparently does not work as expected.
When will you guys from Microsoft learn to use plain old valid-syntax-URLs again?
