Hang Chat, no error messages

[bugsmafia]

Good time. Do not know much English, I translate with Google translator.
I have a problem with chat. The problem is that, if left open chat and nothing to write, chat freezes and does not return any message to it, until such time until the chat that you can not write.
Once that is written at once now loaded all messages that did not come until the chat is frozen.
What to do and how to fix this bug?
It is necessary that the message would always come and chat and always did not get up after 5 minutes of inactivity.
