Try emptying the caches or moving the Safari plist out of the. Prefs folder. I haven't seen Safari 4 crash since I installed it!
BTW, I also have the cache set to zero bytes. That's one less operation/place for app to worry about!
Also, know nead too upollogiez, eye uzd two mayk erorz awl to ofton! Butt nauw Ie blaim sumwon ellce!
How does one do this.
