Here is one approach.

w = 40; nb = NotebookCreate[];

s = "This string will scroll continuously across the screen--like a stock \
market ticker tape--until you click on a notebook other than this one showing 
the scrolling display (e.g., click on the parent notebook).  " ;

While[SelectedNotebook[] == nb, NotebookWrite[nb, StringTake[s, w]]; 
s = StringJoin[RotateLeft[Characters[s]]]; SelectionMove[nb, All, Cell];]

Also, check out the behavior when you click in the display notebook.
