Hate to necro an old thread but I'm having trouble with this in 2012! My opponent vitals frame is at the bottom of my screen and it often stops me from clicking buttons on the main bar (8 through =). It appears that the transparent lower portion of the opponent vitals frame is overlapping the main bar, preventing the buttons from being clicked.
Any suggestions as to how I can fix this without moving the opponent vitals? It doesn't seem to do it all the time.
