I have a similar bug. When I type in chat I can see the text but it doesn't transmit when I hit Enter. Switching to another chat channel then switching back fixes this. It happens relatively frequently. Haven't found a solution yet. I'm assuming it's related to what you're experiencing.
Rarely anything worth seeing in it anyway (Fleet and Team chat exluded).
Crap (and VERY old) Gorn jokes, "my country is better than your country" arguments, player A calling player B a troll and players expressing their sexual frustration in various, often bizarre ways. Rubbish.
