I didn't have any problem and my screen automatically restored to the original state but you can always hit control-r to refresh. However, did you try this "clear;sh vi <filename>" which clear the screen first then sh will start you up with new process for vi which is better in my opinion. Try it if you dare. Edmond Ying
