Cant Clear listbox While Item Selected

Hello Today I Was Experimenting With Wpf And I Found That When A ListBox HAs A Selected Item It Will Not Allow It To Be Modified

        private void Button_Click_7(object sender, RoutedEventArgs e)      {          ScriptBox.Items.Clear();          Functions.PopulateListBox(ScriptBox, "./Scripts", "*.txt");          Functions.PopulateListBox(ScriptBox, "./Scripts", "*.lua");      }  

(Im New To WPF So It Would Help A Lot TO Find Out Why This Happens)
