@Mac442: To clarify some things for you, Onyx is not a third-party plugin; it's a completely separate program that only runs when you tell it to, so it cannot be the cause of something it has no interaction with. Also, disabling Java is not what I've ever suggested. I
did suggest disabling JavaScript, which is entirely different. It is also advisable to disable Java, since relatively few sites use Java at all, so there's no reason to have it running if you don't need it; it tends to make Safari unstable and crash.
At the same time, I'm not having this problem, so I don't think anyone can say definitively that it's a "bug" in Safari 4.03 on Tiger, Leopard, or both. We just don't have enough information to draw a conclusion yet. If you think it's a bug, report it to Apple.
