cool25: are you sure? I have StuffIt Expander running just fine, it seems...
Also. StuffIt (.com) has just released the 9.0.2 updater for StuffIt Standard and Deluxe. (Just download the 'updater' for StuffIt Deluxe, it should also update StuffIt Standard just fine from the ReadMe.) If you haven't yet got Expander 9.0.x, I suggest to get StuffIt Standard at least. It's a drag to get it from stuffit.com, I hear, but it certainly helps.
