unable to right click to leave dungeon
 

For some reason I am unable to right click on my portrait to leave a dungeon or set class as dps/healer/tank in BGs. I am not sure if this is known but is there a work around to the right-click your portrait so you can leave a group withthe drop-down menu blizz UI provides? thanks in advance.

Each unitframe has three clickable fields.

To open the menu, try to right click the power bar.
