Using OSX 10.7.3 with last updates.
I think you have a corrupted System Preferences .plist file

You can remove the current .plist file in ~/library/preferences/com.apple.systempreferences.plist drag that .plist to the desktop (as a backup) and try System Preferences again. It will automatically create a new, working .plist file.
