I don't have a TPU manual at hand, but I think that Current_row actually
returns the position on the screen. Anyway, it seems me to like Current_row
- and Current_column - send escape sequences to the terminal to ask where
the cursor is. I wrote an own "down-arrow" like:
   IF Current_row < Bottom THEN
      Cursor_vertical(1);
   ELSE
      Srcoll(Current_window, 1);
Keeping the down-arrow key pressed, could result with the cursor in the
message window. Changing Current_row to Get_info(Current_window, 
"current_row") cured the disease.
