From 1.7.5, but even in 1.7.6, all 10 icons at the bottom of the chat field are gray. The four icons from the right, "Popup", "Update", "Settings", and "Close" work, but the other 6 icons no longer work. Personally, I often use the "left/right display switching" option on the far left, so you can do it from the settings, but it's a bit inconvenient.
