Systems and methods for providing a multi-window application to a user over a network are provided. An exemplary method includes presenting a first frame to the, the first frame containing application logic. The method further includes presenting a second frame to the user, the second frame containing user interface logic. Steps in the method create a relationship between the first frame and the second frame allowing the user interface logic of the second frame to use the application logic contained in the first frame. When an indication is received that the first frame is to be closed, and an application-specific condition is true, the application logic is transferred from the first frame to the second frame using a command, while preserving the state of the second frame. The first frame is then closed.
