         7 . The client apparatus according to  claim 1 , wherein the control section causes the display device to display a part of the communication status bar area the content of which is changed. 
     
     
         8 . The client apparatus according to  claim 1 , wherein the control section causes the display device to display the content of the communication status bar area in a predetermined position. 
     
     
         9 . The client apparatus according to  claim 8 , wherein the control section causes the display device to display the content of the communication status bar area based on a predetermined layout for the communication status bar area. 
     
     
         10 . A computer system, comprising:
 a client apparatus according to  claim 1  and a server apparatus,   
       the server apparatus comprising:
 a storage device that storages the screen data of a display screen of the server apparatus corresponding to the requested service; 
 a transmission section that obtains the position of the communication status bar area in the screen data and transmits the position of the communication status bar area to the client apparatus; and 
 a screen data transmission section that transmits the screen data to the client apparatus. 
 
     
     
         11 . A non-transitory computer readable program storage medium which stores a program to be executed by a computer of a client apparatus for requesting a service to a server and receiving a result corresponding to the request from the server, the program comprising:
 receiving step for receiving screen data corresponding to the result of the request and a position of a communication status bar area;   a display step for displaying the screen data on a display section; and   
       a control step for detecting a change of content of the communication status bar area so as to display the content of the communication status bar area when it is detected that the content of the communication status bar area is changed. 
     
     
         12 . A display method to be executed by a computer of a client apparatus that requests a service to a server and receives a result corresponding to the request from the server, the method comprising:
 receiving screen data corresponding to the result of the request and a position of the communication status bar area in the screen data from the server;   displaying contents of the screen data on a display section; and   
       controlling so as to detect a change of content of the communication status bar area, display the content of the communication status bar area produced by cutting out the position from the screen data when it is detected that the content of the communication status bar area is changed. 
     
     
         13 . The display method according to  claim 12 , wherein the controlling display the content of the communication status bar area produced by cutting out and uniting the predetermined areas of the communication status bar area when it is detected that the content of the communication status bar area is changed. 
     
     
         14 . The display method according to  claim 12 , wherein the controlling display except for the status bar area based on the screen data on the display section when it is not detected that the content of the communication status bar area is changed. 
     
     
         15 . The display method according to  claim 12 , wherein the controlling hides the communication status bar area displayed on the displaying when it is not detected in a predetermined period that the content of the communication status bar area is changed.
