I made a reply in inbox, then lost it from the thread.
In inbox, I use the "reply" link on this post, the last in the thread.
then the result was
Sorry for there is Japanese in screen.
I replyed to szeigen, but made to MichaelHeider, there is no post from him in the thread.
On Winodws7, Firefox40.0.3
I don't know this is related or not, I logged in as "always logged in" on this PC, and I change the language in preferences Japanese to English on another PC, but the page is stay Japanese since not reloaded yet.
I noticed just now, there is "3 hours ago" in top line of screen, it is already changed to English, but other components are Japanese...
