Well, that's it. If I add a new item afterwards the remaining item gets replaced by the new one, but if not it remains visible and selected (it was selected before). TListBox.Items.String[0]:='' doesnt work - probably because the item internally doesn't exist anymore? Is this a known error or am I doing something wrong?
Best regards,
Victor
PS: I forgot to mention, I'm using Lazarus 0.9.20.
