US Patent 8959446 Information processing apparatus and method of controlling the same

When a plurality of overlapping windows are displayed on a display screen, each window is displayed in a convenient state for a user operation, thereby reducing the load of the user operation. Upon detecting an object drag operation, an information processing apparatus displays the window of a predetermined application, which is displayed behind another window, as the topmost window. At this time, the window of the predetermined application reduces its size or changes the display position so as not to interfere with the other window displayed in front of it.
