HI,
You didn't mention trying any troubleshooting that you have tried.
Sorry to hear that Safari 5 isn't working for you. Is it possible you have any third party Safari add-ons that aren't compatible with the update that were compatible with the prior version of Safari.
Check here just in case.
Safari: Add-ons may cause Safari to unexpectedly quit or have performance issues
Try troubleshooting the Safari .plist file. Go to the Safari Menu Bar, click Safari/Preferences. Make note of all the preferences under each tab. Quit Safari. Now go to ~/Library/Preferences and move this file
com.apple.safari.plist to the Desktop.
Relaunch Safari and see if that makes a difference. If not, move the .plist file back to the Preferences folder. If Safari functions as it should, move that .plist file to the Trash.
If you didn't repair disk permissions after updating to Safari 5, it would be beneficial to do that.
Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.
