A first information processing apparatus executes an operation corresponding to a message entered thereto. Upon completion of the operation, the first information processing apparatus sends a notification to a second information processing apparatus. The second information processing apparatus stores such notifications in a memory. The second information processing apparatus also receives a message, and upon expiration of a predetermined time after receipt of the message, the second information processing apparatus determines whether the memory contains a notification relevant to the received message. When the memory contains such a notification, the second information processing apparatus avoids execution of an operation corresponding to the received message.
