Message Bug, Please help/fix

I have a quite annoying bug for the last one month. I have Murder's name on my screen at all times, even though he doesn't write me a message, it just stays there. I talked to him and he said there are other people that has the same problem. When i turn it off, it pops up back again after few seconds. I am tired of seeing a little name tag on the right side of my screen at all times. I can't click on some stuff before closing it, and as you can imagine it is frustrating to have it. I am assuming it shouldn't be very hard to fix. Please help!
