If the state of a first application program is inactive, the control unit determines whether or not the event notified to the first application program is a key input event caused by a key other than an active switching key. If it is determined that the event is a key input event caused by a key other than the active switching key, the control unit causes a clock circuit to time a predetermined time period, and performs control so as to omit part of processing by the first application program, or to provide a predetermined wait time in between the processing by the first application program, until the predetermined time period is timed out."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus for displaying a multi-window system having an active application and an inactive application","description":"In an information processing apparatus according to the present invention, a control unit notifies each application program of a key input event in a multi-window system.
