I must be missing something obvious. The items in my listbox are disabled (I can't click on them). Here's the properties of the listbox:

- RowSourceType = 0 - None
- Sorted = .T.
- Enabled = .T.

The listbox is populated in the Init of the form with AddItem.

UPDATE: Found the problem. It was not so obvious afterall. It turn out that the first character of the items I was inserting started with a "\"... >:-(
