Hi Keith, I kind of doubt it's that file, you can't download it per se, but it Likely could be extracted from your Install Disc, (possibly the big 10.4.11 Update too), using Pacifist...

My bet would be one or all of these...
Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, then move these files to the Desktop, then Trash the original of the last one(s).
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Users/YourUserName/Library/Preferences/ByHost/Users/YourUserName/Library/Prefer ences/com.apple.CharPaletteServer.plist
/Users/YourUserName/Library/Preferences/com.apple.systemuiserver.plist
/com.apple.HIToolbox.<12digitHex#>.plist
There may be more than one of the last one above.
You may need to check show it in the Menubar again.
