For the past few days, whenever I try to respond to someone's status update, I'll type something out, then hit the button to post it, but nothing seems to happen. It still seems that I'm in edit mode. I then hit the button to post it again, and again it seems nothing happens. If I then navigate elsewhere with the browser, then return to the page, however, I find that the response did post - and there are repeats for every time I hit the post button, which I then delete. Is this happening to anyone else?
