Abstract
Abstract A virtual screen processing section sets a virtual screen larger than is allowed by the display performance of the screen of a display section, displays a part of the virtual screen as a real screen on the display section, and controls the position of the real screen as needed in accordance with an operational input made by using the information input section. A window processing section arranges display screens based on the execution of individual applications as application windows on the virtual screen. A list display instructing section instructs the display of a list of application windows. A list display processing section collects window information including application information indicative of running applications and position information of the application windows of the running applications on the virtual screen, application by application, and displays a window information list based on the window information.
