My UISlider Thumbs stop responding to dragging if the touched collision area goes beyond the frame of the slider itself - the effect of which is, you can only reach 100% if you select the lower half of the slider Thumb, and 0% if you select the upper half.
Obviously using a collider on the Background sprite gets around it, but then you have instant-click slider setting which isn't always desirable.
Is there a solution/workaround to the Thumb issue in particular?
