Annoyingly, I couldn't find, at least in any of the official guidelines for any 
desktop environment I looked at (OS X, GNOME, KDE, Windows) any discussion of, 
for example, a "derived" window, where you have a main window with a document 
(or a data store of some sort, e.g. a mailbox), and, for example, ask the 
application for a statistical analysis of the document,w which pops up in a 
separate window.  Does that get destroyed if you close the window for the 
document from which it's derived?  Does it get minimized if you minimize the 
document window?  (And what happens, at least in OS X Lion, if you make the 
document window full-screen?  Lion's full-screen is a bit more full-screen than 
the Windows/KDE/GNOME/etc. full-screen, in that it's supposed to be sort of 
like iOS, where the document window is all you have.)

Neither Excel (at least on OS X) and Numbers pop up graphs as separate windows 
- that was the obvious example I came up with.  I tried getting document 
statistics with both Word and Pages; Word pops up a *modal* window with 
document statistics, and you can't close the document window or do anything 
else with it until you close the statistics window, and Pages pops up an 
"inspector"-style window, which isn't modal, but you have only one of them, and 
it displays the statistics for whichever document window you've just selected 
and goes blank if there are no document windows.

So I thought "hey, what does Network Monitor do?"  It doesn't seem to have any 
obvious built-in statistics, but it has "Experts", which appear to be like our 
statistics taps.  So, after downloading and installing one of the "Experts" (a 
bit of a clunky procedure), starting it (a bit of a clunky procedure - I had to 
save the capture to a file first), discovering that I needed to install a .NET 
widget for the "Expert" (a bit of a clunky procedure, as the dialog telling me 
that didn't pop up on top the first time I tried it), and installing the widget 
(a bit of, well, you know the drill), it popped up a statistcs window - which 
remains behind even after you close the window, and even after you quit Network 
Monitor (probably because it's running in a separate process.
