Really annoying in client chat issue (bug?)

I tend to have a lot of chat tabs when I'm logged on, and you know how it does this? http://puu.sh/n68V6/110b5198fa.jpg

Well after some patch, even if you close all but one tabs, they still show up like that making it hard to figure out who you're talking to!

Like so: http://puu.sh/n68WO/174ef2706f.jpg

Who is "Z...."? Who is "Dr ..."? I don't know, it won't tell me the names unless I re-create the tab which takes a bit because my friends list is full!

Hopefully this will be fixed soon!
