When I booted SL for the first time it gave me a bunch of warnings that I needed to delete a bunch of fonts because they were causing display conflicts with system fonts. One of them was Helvetica (and of course I thought to myself why the %^&$ would I delete that??)! So I clicked the allow conflict button on all the alerts. But, now I'm having a problem with the administrator password prompt.
How can I fix this?
