A couple of things... You can only it when drawing from the deck, so you need to single click, then when the card is face up on the deck, you need to drag it to the Turn Order window When putting it on the turn order window, you need your mouse/card directly over where the number is in the turn order. If you look closely, you will see the number slot turn yellow and then you drop the card on the number. It took me a bit to figure that piece out as well. I also wish it could be updated to allow people to place cards in the Turn Order from cards in their hands, but can't do that yet, only when drawing directly from from the deck. I hope this helps.
