Thanks Ricky, Kyle and Rob.
I do appreciate your comments, but none of this addresses my question.
I started working from TN2062 several months ago and only after a ton
of research and experimentation found that this alone does not meet my
needs (for reasons I won't get into here). I do, in fact, still have
the kiosk stuff outlined in that technote implemented and have the
GCaptureAllDisplays stuff on top of that.
Anyway, that's water under the bridge.
What I really want to know is how I can get notified when windows
become active in my app.

I have a need to find a way for my application to find out when

The specific case I'm currently looking at is when the print
dialog is opened and the user chooses "Save as PDF...". This
action will open a file save dialog and I need to know when this
happens. I don't see any events that can notify me that this
window has opened.
Of course what I really want to know is when a window is supposed
to become visible.
OK, I won't leave you wondering...
I'm working on a kiosk application and my main window is far above
the print dialogs so they don't display. If I can know when they
are to display I can grab them and pull them forward. Currently
when my main window delegate received a windowDidResignMain:
message I go look for "lost" windows and pul them forward. This
gets me the print dialog but since I am no longer active any
secondary dialogs get left behind my main window. Thus locking up
the machine (time to reboot).
I'm using the method outlined in this link to make my application
very-front-most...

I'm pretty sure this is no longer the recommended way to do a kiosk
application. Instead, you can use SetSystemUIMode to hide the
menubar
and dock (or replace the Finder as the first app launched).
TN2062 < http://developer.apple.com/technotes/tn2002/tn2062.html >
has
more information.
Definitely go this route (it's what I do). I also recently added
PDF generation features in my full-screen app and it works a-ok with
all AppKit dialogs.
Capturing the screen is primarily used for games such that all UI
will be rendered/controlled without AppKit. In fact, you cannot
expect captured screens to work at all with AppKit. It may or may
not work depending upon the computer, graphics card, etc.
