## Abstract

Systems and methods are provides for changing a user interface for a multi-screen device. The user interface can change based on the movement of a window. The system can receive a user interface event that modifies the display of windows in the user interface. Upon receiving the user interface event, the system determines if a window has been covered or uncovered. If a window has been covered, the window is placed in a sleep state. If a window is uncovered, the window is activated from a sleep state. A sleep state is a window state where an application associated with the window does not receive user interface inputs and/or does not render the window.

## Claims

### Claim at position 1

### Claim 21

A non-transitory computer readable medium, having stored thereon, computer-executable instructions executable by a processor, the computer-executable instructions causing the processor to execute a method for changing a user interface for a multi-display device, the computer-executable instructions comprising:
instructions to receive a user interface event in a first display area of two or more displays areas of a display device having a composite display area;
instructions to determine that a first window is to be displayed in both the first display area and a second display area of the composite display area based on the user interface event;
instructions to determine that a second window is to be covered by the first window in the first display area;
instructions to determine that a third window is to be covered by first window in the second display area;
instructions to place the second window into an inactive state in the first display area in response to the second window being covered by the first window;
instructions to place the third window into an inactive state in the second display area in response to the third window being covered by the first window;
instructions to place the first window into an active state after completion of the movement and expiration of a timer, the timer starting upon completion of the movement; and
