Closing a window

• Move your mouse pointer to the last of the three icons.  After a short delay you will see a popup explaining that this is the Close icon.
  
  
  

• Click on the Close icon and the program will close.  It is not displayed within the Taskbar as a minimised icon. The program is no longer in your RAM (Random Access Memory).  RAM is where all your active programs are stored when they are running.  If you close a program the program is removed from RAM but you still have a copy of the program stored on your hard disk. To re-run the program you will need to open the program from disk.
