I suspected that I might get myself into trouble when I wrote that. However, I was not lying, and I have seen many posts that back up what I said (no, don't ask me to go and find them). I did NOT say that The King was the only engine that supported this feature. I said that The King was the only engine THAT I KNEW OF that supported it WELL. And where did I say that this was the "most important commercial feature"? I own Fritz and Ruffian, and they (to the best of my ability to judge) do not handle this feature as well as The King. I did not know that Shredder did it until Stefan mentioned it in this thread -- and he agreed that it is a very difficult task to implement properly. jm
