Hi, There is a problem. To replicate it click on the red button that says "Reply To Thread" at the bottom left of this topic. Type anything you want and then press the button again to post it. The message vanishes. Obviously you are not supposed to click on the same button again but because the label says "reply" and because it is red and big, you click on it. To correct this problem I recommend the button label to be changed to something else like "show message editor".
