Starting with AmigaOS V37 the Workbench offers a library with some useful
functions for applications. Although this is a _BIG_ improvement over the
old Workbench there are still some important features missing.  The  most
annoying one is that an application with an open window on the  Workbench
screen prevents the closing of the screen, e.g. after pressing  "Use"  in
the ScreenMode preferences editor.

To circumvent these programs have either to  patch  the  CloseWorkBench()
and OpenWorkBench() functions  in  the  intuition.library  or  to  add  a
notification for the screenmode.prefs file. The ideal solution would be a
new App* message from the Workbench, but  as  we  all  know  a  Workbench
update/rewrite is not very likely in the near future :-(

ScreenNotify offers  an  intermediate  solution.  It  patches  the  above
mentioned functions and offers a notification service for  clients.  This
hides the "dirty" things in one location and offers a clean interface  to
the outside world. Clients only  have  to  close  their  windows  on  the
Workbench screen after receiving a CLOSE notification. They may open them
again after receiving an OPEN notification.

Additionally ScreenNotify patches CloseScreen() and PubScreenStatus(). It
can therefore offer a notification when a  public  screen  is  closed  or
opened. This may be useful for utilities  which  open  their  windows  on
public screens.
