Couple of issues have me little confused? :)

[Therendil]

I have seen the issue with the control buttons not appearing until I min/max the experience window. I haven't seen it enough to be sure of the circumstances, but I think it happens the first time I set up the UI for a character, or if I completely reload the UI. For me it happens rarely and stays fixed after I cycle the experience window.
