If you click on More on the Smilies box to the right of the editor when you post a normal reply and not quick reply, you have all the smilies there. It opens in a new window and they are showing for me.
You can also see all smilies by clicking the arrow to the right of the smilie in the head of a message you are creating (Next to the A with a black line underneath).
To get the full functions of posting a message and not the quick funtions, click the button that says Post New Message / Post Reply to reply to a post or start a new one.
