Thanks, I'd just worked out how to do it with the class designer (I'd been making the mistake of using DIMENSION when adding the new property)

Doesn't using a copy on the form defeat the point of OOP though. For each instance of my modified combobox I would have to manually place a copy of the array on the form + create a unique name for each copy. If I make it a member of the modified combobox, the creation & initialisation is automatic & there's no need for a unique name.
