A personal experience thing in VFP 5. I haven't done this in awhile, so I don't know if the behaviour has changed.
When checking if an item is selected, the selected status would switch on some items, most of the time I noticed it would be unselected. If I made sure the focus was on the listbox with a SetFocus() and the problem went away.

Not sure if this will give you better results,
