When enabling wordwrap on a listbox column, it is important to note that if the row height is 1 line then the word wrapping will not be visibly apparent.

In order to for the wordwrap feature to function there must be more than a single line of space available to display the text. Increasing the row height of a list box is accomplished by using the Property List for the listbox and adjust row height within the Coordinates & Sizing section.
