Abstract: An information-processing device according to the present invention displays plural windows in a certain arrangement. The information-processing device selects one of displayed windows as a selected window, and in response to an operation to specify a direction, sets a window located in the direction as a selected window. The information-processing device also, in a case where plural windows are displayed in a certain arrangement, changes the arrangement in accordance with a predetermined operation. The change may be made in a regular manner or according to a random pattern. For example, in a case where window W1 shown in Fig. (a) is a selected window, a desired window (a window a user wishes to select) is window W5, and arrangement is changed, the arrangement is changed to an arrangement shown in Fig. (b) or (c) so that a number of operations that is required for a user to select the desired window is reduced.
