Lawrence,
Since the Nomads Designer interface is the same on Windows and Linux (running WindX), I am going to assume the difference in the Nomads Designer on your system is probably due to running two different versions. In v12 we revamped the listbox interface to make it easier to define Report View listboxes, allowing you to select it as a list box type on the Display tab. Prior to that, to define a Report View listbox, you had to select List View as the listbox type on the Display tab, then go to the Attributes tab and check the List view with report format option. The Format button on the Attributes tab allowed you to specify headings and column widths.
There is also a Formatted listbox type, but it does not have column headings.
