In previous versions, TrackBarEdit incremented or decremented its value when a user clicked a line next to the thumb. The increment and decrement value was specified by the LargeStep property. We decided to change this behavior so that the thumb immediately moves to the clicked position on the line, like in modern Windows UI applications. The LargeStep property no longer affects TrackBarEdit behavior.
To roll back to the previous behavior, set the TrackBarEdit.IsMoveToPointEnabled property to False or disable the global CompatibilitySettings.TrackBarEditIsMoveToPointEnabled option.
