Good day, thank you for your answer.
I am trying to do exactly the same stuff like in video. After inspecting further I found out that when running Designer - my graphic card starts running at 100%, what slows down the PC (I am running windows 7x64 pro).
I installed Designer on another PC that runs on server2008r2, there I get a different error dragging time column (see attached file).
Best regards, Mikhail.
