    Abstract: A terminal computer used as a workstation has a display unit which displays a desired number of windows on its display screen, allowing the windows to overlap one upon another. Plural pieces of data specifying the positions and sizes of the windows are stored into a memory. Data representing the display priorities of the windows are stored into another memory. A coordinate input device, known as "a mouse," is manually operated by an operator, and a cursor displayed on the screen of the display unit moves with movement of the mouse on a flat surface. The most current coordinates of the cursor on the screen are stored as present-cursor position data into a memory. A window presentation controlling section is provided for comparing the present-cursor position data with the positions and sizes of the windows. When the cursor is detected to have moved into one window on the screen, the window presentation controlling section controls the display unit to automatically move this window in front of the other windows on the screen. In this case, the frontmost window is entirely visible, while the other windows are hidden at least partially behind that window.
