When an annoucement is created it goes to the bottom of the page always...even if the
display order may have been adjusted by clicking on the 'Date' column.
If you navigate out of announcements to another tool and come back to announcements,
the new announcement still remains at the bottom of the page. But if you refresh the
annoucement page, by clicking on the 'arrow' icon beside the page title
'Announcements', the page reefreshes and the order of announcements is adjusted and the
newest announcement gets displayed first. If you do this even after manually changing
the order of announcements from oldest ot newest, it changes the order from the newest
to the oldest.
But a new one always goes to the bottom of the list.
