If you are creating a page for the first time, click Show Changes causes the loading circle to spin forever. Ideally it should inform you that there are no prior revisions rather than just having you wait and wait. Noticed it when I forgot that this was the first revision of a page and went to go see the diff to give it a good edit summary.
