Fire wp_auth_check_load() from admin_enqueue_scripts instead of admin_init so that it can access the current screen object.

Black list the update and upgrade screens.

Allow plugins to white/black list screens via the wp_auth_check_load filter.

Remove the Spellchecker button from TinyMCE.

A WordPress plugin could still re-enable this TinyMCE plugin if they wanted.
