I saw the headline on MR's first page and decided to get Safari 4.0.2. So I fired up SU and it found Safari 4.0.3. I clicked the Install button and then SU stopped responding and I did a force quit. I tried again, but the icon bounces on the dock and then just sits there with the little light out, like an unused app. I repaired permissions and cleaned some caches with MainMenu. I'm running 10.5.7 on a mid-'07 2.0 GHz mini, if it makes a difference. What is going on?
