   It doesn't use color, it only prints characters.  That's why, if the   
   screen was recolored, the characters will show up using the previous   
   coloring.

   That's internal to CRT only.   
      
   What you should be doing is saving the screen contents when starting,   
   then restoring them on exit (along with the correct screen mode and   
   cursor location).   
      
   That sounds like the solution. How does one do that?
