Without commenting on the wisdom of blowing past exceptions 😉, I’ll note that: 1. NSExceptionHandler doesn’t allow you to prevent uncaught exceptions (whether truly uncaught or caught by one of AppKit’s last-resort catches) from being reported to +reportException:. It in fact goes out of its way to make sure it does not impede this 2. Buuuut… the default behavior in Cocoa of an uncaught exception is to ignore it. You’re seeing this dialog because you have the user default `NSApplicationShowExceptions` set somewhere. (Use `defaults find` to help find out where.) It’s not on by default, but you may have turned it on at some point because of the aforementioned wisdom HTH, Matt _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
