Arrow icon settings

Hello;

      My arrow icon, that you can use to allow your view to become perpendicular to; the x,y,z red, green, blue directions, has lost it's setting. Now when I click on tlhe arrows icons it just rotates 15 degrees which is usless to me. Does any one know how to control these settings, I must of hit something & changed it somehow?

Thks in advance;
