Did anyone ever find out what was going on here? I have a friend that just installed Safari 1.0 and is having the same problem? (Crashing all the time, pages not loading right). I told him I would see if anyone here knew about it? Has anyone tried logging in as a different User and then trying safari again? I personally havn't had any problems with 1.0.

For reinstalling the older version, you have to make sure that the Safari.pkg file is removed from your Library/Receipts folder. Then the older version should reinstall. Give it a try. Good Luck.
