I did try this - first removing the da#misc#realize () above, then
adding it to 'view_drawing':

let view_drawing () =3D
  let da =3D create_drawing_area () in
  List.iter area#remove area#children;
  area#add da;
  da#misc#realize ()

This now dies in a different way. The program crashes with this error
message:

Fatal error: exception Gpointer.Null

Can you tell me how to get this program to work?

Rich.
