How to Insert Controls
To insert controls:
Make sure that the parent object (usually an Info Window, Dialog Box or Column Box object) has a horizontal or a vertical orientation. If the parent object has an XY orientation, you cannot predict the location of the control you are adding. In the case of a horizontal or vertical orientation, the added control will be the last object (i.e. it will have the highest Position number).
From the menu bar, choose Insert and the corresponding option.
