None of the Safari drop-down menus work - including the preferences menu.
Added any extension recently?
Try resetting Safari and emptying safari caches.
I haven't added any extensions to Safari that I know of. In any case, I closed Safari, put the Safari cache in the trash, emptied the trash and restarted Safari. Unfortuantely that didn't change anything. But, thanks for the suggestion!
