Fix Version/s: None
When you press tab somewhere in a settings menu, a button will be selected.
But when you click a different than the one that is selected, you press tab again,
you will see that the current selected button is the one that was clicked.
This button will be blue, but the previous button is also blue.
You cannot really see which of the two buttons is really selected.
The previous button will stay blue until you press tab and the real selected button overlaps the "ghost" one. Then every thing is back normal.
