When posting a comment to the dashboard, profile or photo newsfeed, the smiley icon duplicates (replacing the file attach button, where applicable). Refreshing the page clears this up. See attached - first image (smileys-before) is before adding a comment, second (smileys-after) is once the comment is accepted. Sometimes it will then make three icons ( if I close out the comment panel and open it again without refreshing the page ).
