Sergey,

Having written the article and having seen Ed's code, if I were currently looking for a solution to this problem, I'd probably use Ed's method with the necessary additions to display the original instance of the application. I say this because Ed's solution requires less code overhead, and, therefore, would be easier to maintain.

Admittedly, I still use my solution, but only because it's the method recommended in the Platform SDK.
