Chat disappeared

[tylor]

I don't know if this bug or not, but I had chat working last weekend, and then it just disappeared. I am connected to server (as icon in bottom corner says), chars in vault update, I even can see list of people online when I try to write a message to chat. When I start playing, game writes that it connected to three usual channels (tome,global, tome-spoiler). But chat log is empty, and when I write message, it does not appear (edit: sometimes, randomly, it does O_o). All squares in Chat Message Filters are green, as well as in Chat Channels. Internet is working ok otherwise.
