You may have read my earlier post, where I described Safari unexpectedly quitting upon closing any Safari window. Nobody was able to offer a solution, and I only found one more case via google. So I went back to Safari 2. Everything worked great again except the google search contextual menu item. I reinstalled 10.4.11 from the stand alone installer, hoping for a different outcome. Safari 3 still crashed. After checking the error log, it seemed some files were missing. I then did a clean Tiger install (archive and install), followed by the 10.4.11 update. I opened Safari and closed a window and it unexpectedly quit, on a fresh system. I stand by my original opinion that Safari 3 is a buggy piece of crap. Flame on!
