Folks, I just did some seasonal adjustment with the latest Windows snapshot (build date 10/8). With one series I got a warning about at least one significant trading day effect. I had a look, closed the warning box & adjusted the rest of my data. Some subsequent data also generated a warning, but the warning box was shrunk - just the triangle-exclamation point sign and a "close" button.
