Thank you for following up with this here. If I interpret your post correctly, r2xmann, you're saying that since applying the combo updater rather than the incremental update, you are now able to restart your mac normally. It also sounds like you're saying that now, even after a permissions repair with AppleJack, you can restart again afterwards. It sounds like the 10.5.7 combo update fixes something.
Starmanjay, your problems appeared when running Leopard 10.5.5. Was that a combo update, or an incremental update (through Apple Software Update...)?
