If I have the Class View and Solution Explorer open together when I initially select a namespace in the class view all code files in Solution Explorer related to that namespace are highlit.

But selecting another namespace in the Class View doesn't update the highlights in Solution Explorer. To get that to work I have first to select an actual object in the Class View then select a namespace.
Although just a minor annoyance with an otherwise very useful feature - does anyone not see the behaviour or know how to avoid it.
