Not necessarily the user's fault; I've seen it happen often that LaunchServices just decides to make some other app the default, even though there's an OS-provided app that really *should* remain the default until someone explicitly changes it. This is particularly bad for the apps that live in /System/Library/CoreServices (like DiskImageMounter, in your ISO example), as some of those seem to be still using CFBundleTypeExtensions in their CFBundleDocumentTypes dictionary instead of a UTI, and LS always seems to prefer apps that use UTI over ones that don't if no explicit default is set, so if your app uses a UTI for those types, control will be handed over to you instead of DiskImageMounter simply because the user downloaded your app. My solution was just to check the file associations on startup, and if it's set to me, change it back to the OS-provided app. It's a kludge, but it's stopped the angry e-mails, and all is right with the world.
