Ken,
One other thing you might want to be aware of - NSApplication has an
NSApplicationDidChangeScreenParametersNotification which is sent when
the user changes screen resolution or arrangement. You can get this
notification by implementing -applicationDidChangeScreenParameters: in
your application delegate (see NSApplication.h). This will let you
resize/reposition your windows as necessary after a screen configuration
change.

What do you mean by dual monitor support?
All applications on OS X can run on any monitor. Window locations
in Cocoa do not store correctly in the preferences if they are
stored on a secondary (or later) monitor, but other than that there
are no known problems that I know of.
What specific "functionality" are you looking for Cocoa to provide
WRT multiple monitors?
It's basically a front end to a database which needs to have 2 windows
(i.e. 2 documents), 1 on each screen, both full screen. So I need to
know
the global coords for each monitor (including each one's resolution so
that I can go full screen). It won't have a GUI as such, as it's for
displaying stuff on flat screen monitors hanging on walls, not for users
to actually 'use' (there's another 'normal' app for that). But I'll
check
the NSScreen stuff before I ask any more stupid questions! (That doesn't
mean I won't ask any more stupid questions, just that there'll be a
pause
first!).
Thanks for your help folks,
Ken
