The way the /create/ action of the QTk cards are handled is not good. If a card is created but not connected to a window (perhaps through other cards), it will block.
The solution is to build more asynchronously. The entry point of each card must be added to the /create/ action. When the window create all the cards, it must send the action to each card, with a special action (/setHandle/).
The QTk cards will be more robust for the creation.
