I'd like to add that this is a genuine bug in the Web Console, not the way we meant it to behave. `window.Object instanceof Object` is meant to be true. See bug https://bugzilla.mozilla.org/show_bug.cgi?id=774753 about it. Use Firebug's console to avoid running into those issues. _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
