None of this code was written by me, so I don't know the reasoning behind the design. We have a popup that shows an NSWindow with an NSBrowser in it. There is a NSPopUpButtonCell subclass that handles the click with trackMouse:inRect:ofView:untilMouseUp:. This trackMouse method calls [NSApp run].
When a click happens outside the browser window, it calls [NSApp stop:nil] from our NSWindowDidResignKeyNotification observer for the browser window. At that point, it seems like the app is actually trying to terminate, because all hell breaks loose - release builds crash with no crash log and debug builds crash with a stack of:
#0-9 is in the dtor for one of our global objects.
#10 0x91a1cebf in __cxa_finalize ()
#11 0x91a1fdb9 in exit ()
#12 0x957ba692 in NSApplicationMain ()
#13 0x01310fb8 in main ()
This leads me to believe that using run and stop: is the wrong way to do this. What's another way to start and stop a "local" run loop?
