Form Selection List Properties

When creating a Form in NVU Portable it's easy to insert the Form elements. Then when modifying a Form element it's easy to just double-click the element and modify its properties.

However, this doesn't work when trying to modify a "Selection List" Form element. Nothing happens when double-clicking the element and if one goes to the INSERT menu and selects "Selection List" it comes up with all of the properties of the selected element on the page. But, when one clicks OK it disappears.

Getting this to work would be really nice.
