Thanks for the nice feedback, always good to hear that.
Madoron, either unlock the 2nd window (right click->unlock) or create a tab in the 1st window and drag it out of the existing chat window. Both options work fine for me.
Insidius, maybe I messed something up when fiddling with the fonts, although all seems to work fine for me. I don't have a rogue, so I have to ask how this message looked like - like a skillup message? Or was it a message box?
In case it's a setting you changed, I do unfortunately not know how to enable it again.
