Thanks for the reply, John. Just about 30 minutes before your email, I figured out: self.macapp.connect("NSApplicationBlockTermination", self.sig_close) ... which allows me to use the same exit handler that was in use by the standard gtk exit menu item. It turns out that it was a call to gtk.gdk.threads_init() which was causing the application to block when actions were an exit action was invoked via the integration. I'll investigate that further. --phil On Aug 24, 2010, at 7:50 PM, John Ralls wrote: > > In the absence of a handler for NSApplicationWillTerminate, OSX will just kill the process and reclaim its resources.
