Twice today I've tried to REPLY to a comment in the Writers group. It's a reply to a reply, not to an OP. I type in my comment, click the REPLY button and I get a red square about the size of a postage stamp over the button. It has a spinning progress circle in it. It goes away if I click anywhere, but the message doesn't get sent. I've tried this several hours apart, after leaving and re-entering Lush. Is this a known problem?
