Hmm.  This seems very confusing.  I'm not sure what you're trying to do in
your initialization class.  Most of it looks like it belongs in your
document's initialization method.  It looks like your trying to have
CScrollWindow act as a window and a director.  For instance, you init the
scrollPane variable with "this" for both its supervisor and its enclosure.
I'm pretty sure that CWindow assumes that its supervisor is a decendent of
CDirector, which may cause your implementation to crash eventually.  I
must admit tha I haven't quite figured out why your clicks haven't been
dispatched properly, but I though that what I've just said might give you
a clue.  Good Luck.
