Is there any way to turn this off so Safari behaves as it did before? It's odd—Safari only tabs through certain buttons and popup menus, not all (here on 'NN, specifically). But it's still doing it, even though I have my Keyboard & Mouse System Preferences set (^ F7) to only tab through lists and text boxes—which is what Safari [i]used/[i] to do. I would like Safari to return to that state. Any ideas?
