@Doomdice : I didn't understand. Did you try what I ask for you to do? Can you explain? Thanks for understanding.
@Shade ~ : Hahaahah
@Dope23 : Did you mean the chat window? If you did, please update your client by reopening your launcher. There is a new option for keep the chat window activated.
If you want to keep the chat opening and closing when you send a message, and you can't reopen, just use your mouse for pull it up. Sometimes the chat loses the focus. Unfortunately, we don't know why, but follow these steps I said for fix, because it works.
