When is DispatcherUnhandledException and AppDomain.UnhandledException insufficient (WPF application)?

Question

I connected both of them, but sometimes my application still crashes and just calls the Windows “exception occurred” dialog. When I click OK, the application just exits. Under what circumstances will the exceptions not occur with these two handlers (in a WPF application)?

I should mention that I am doing a bunch of COM interactions, so I always suspect :-)
