Thank you everyone for your responses and discussion. I'll take a look at all of the resources listed by responders, and pursue it further with DTS. In conclusion, I'll add what my opinion is of the knobs and switches on the machine here.
Here's what I find interesting -- if I set the NSWindow sharingType to NSWindowSharingNone, then screen capture with another capture app (like ScreenFlow -- the only one I've directly tested) does not work. It still indeed does capture, but it captures my desktop as if my app was not running or visible. Everything else on my desktop is captured, but my app is nowhere to be found. In addition, if I attempt a Command-Shift-4-SpaceBar (to capture the window), then this does not work -- in fact, OS X presents a dialog saying that this operation cannot be done (see the link below -- note this is nothing that my app presents). https://www.dropbox.com/s/0i02n3bkuhg0160/Screen%20Shot%202013-03-07%20at%208.11.16%20AM.png However, if I Command-Shift-4 and then mouse-drag, I can capture whatever is in the bounding box (including the entire contents of the window which was prevented in the other case), or if I Command-Shift-3 I can capture the entire screen (including the window in question). Based on the inconsistency of the Command-Shift-... screen shot behavior, my conclusion is that this is a bug. Completely forgetting any philosophical or design opinions, this behavior doesn't make logical sense to me. To prevent someone from taking a screen shot of the specific window, to the point of the system intervene further with a dialog presented to the user, while allowing the entire contents of that same window to be captured by taking a screen shot of the full screen or a custom bounding box by mouse-drag -- I can't reconcile the logic behind that. So my conclusion is that this is a bug, probably with the enforcement of the NSWindow sharingType. Thanks again or the responses and discussion, both on this list, and offline.
