2-- Look at the icon in the bottom corner of your screen. Is it flashing?
 
1-- No. It isn't.
 
2-- OK. Try closing down all the files you're not using at the moment.
 
1-- But I can't move the cursor at all. My screen is frozen. What should I do?
 
2-- Have you tried pressing the Escape key?
 
1-- Yes, but nothing's happened.
 
2-- OK, you’ll need to reboot your machine. Press Control, Alt and Delete at the same time.
 
1-- I've never done that before. Will I lose all my files?
 
2--You might lose the file you were working on, but don't worry, the help desk can restore it. When did you last take a backup?
