Dave Champion heard you were having trouble making comments.
works every time for me. are you using the app or the desktop? possibly its a leftover from when we had our bug after the update. if that is the case, restarting the browser or the computer or both might solve it, or clearing the cache, which is what my techs told me.
If desktop, which browser are you using? If use Opera, FF, and Chrome. Every now and then, FF 'hangs' but it works on the other two. Refreshing/restarting FF has solved it for me.
