--- Comment #13 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-01-17 12:54:18 UTC --- I assume you were just hitting "refresh" on this page. If you (accidentally) changed the component once and refresh, most browsers will keep your chosen selection in the form, so if you then submit another comment you'll re-submit your choice of 'libobjc'. It didn't happen on your last comment anyway, so you seem to have stopped :)
