How do you add a new column to an existing datawindow in Powerbuilder
<p>I have inherited an old project that was written in PowerBuilder 11.2.  I need to add a column to a datawindow, then add the control to the window?  I have gone into Design->data source and made the change in the source there, and I have also made the change in edit source=>retrieve statement as well (just to be sure).  The form loads fine, I just cannot find out how to add a new column in the design and data windows. I am looking for any help on this at all.</p>

<p>Thanks.</p>
