Re-opening because LabVIEW NXG has been discontinued.
When you align a control that has increment/decrement buttons to other objects on the front panel that do not have them, LabVIEW aligns the buttons with the edge of the other controls. The align objects command should ignore the increment decrement buttons and align the border of the control with the borders of the other controls.
Workaround: Hide Inc/Dec Buttons, align objects, Show Inc/Dec buttons. However not as convenient.
