So Safari died out on me, it would hang up while starting up. I logged in with my sister's account, and it was working OK in there. I thought perhaps my preferences had been corrupted, so I deleted all of my user's Safari prefs. Nothing... I then deleted Safari and downloaded the latest version from Apple's website. The installer said I needed Mac OS X 10.5.2 or later to install, I'm running 10.5.4!! 

So I installed Safari from the Leopard DVD, but now I'm stuck with version 3.0.4. Software update won't detect any updates for Safari, and the standalone installer still asks for 10.5.2 or later.
Anyway, perhaps it's better this way, the last 3 or so updates of Safari had been beachballing me to insanity. Multi-tabbed/multi-tasked browsing had become impossible and I was pretty much switching to the new Firefox. Safari 3.0.4 is working smoothly, but I'm the kind of person who compulsively updates every piece of software on their machine to the latest version, wether there's some improvement or not. Any chance there's something I could do to fix software update? Thanks
