Claim:
An information-processing device comprising: a display control means for causing a display means to display plural windows in an arrangement; a selection means for selecting a window displayed on the display means; a switching means for switching a window being selected by the selection means from a first window to a second window, the second window being displayed in one of directions relative to the first window, the direction being indicated by an operation; and a receiving means for receiving an instruction to change an arrangement of windows on the display means, wherein the display control means, in a case where an instruction is received by the receiving means, changes the arrangement of the plural windows so that a relative positional relationship changes between a selected window that is selected by the selection means and a non-selected window that is not being selected by the selection means, an identifying means for identifying a relevance level for each pair of the plural windows, wherein the display control means changes the arrangement of the plural windows in accordance with a condition that a non-selected window that is not selected by the selection means, which is located adjacent to the selected window before the change of the arrangement is made is not adjacent to the selected window that is selected by the selection means after the change of the arrangement is made, wherein the display control means changes the arrangement of the plural windows in accordance with a condition that a non-selected window that is not selected by the selection means, which is located within a range selectable from a position of the selected window by number n before the change of the arrangement is made, is relocated such that, the non-selected window is not within a range selectable from a position of the selected window by number n, which is smaller than number m, after the change of the arrangement is made, wherein the display control means changes the arrangement of the plural widows so that the selected window is able to be switched to a window having a higher relevance level relative to the selected window by the switching means in a smaller number of switchings.
