I did update the code above [view source], one additional condition needed for hideListTip function as follows: <pre lang="actionscript3"> private function hideListTip(event:*):void { if (customTip != null) { if (ComboBox(event.target).dropdown.contains(customTip)) { ComboBox(event.target).dropdown.removeChild(customTip); } customTip = null; } } </pre> Thank you Phil for your note, it is a fatal of course ..

I see the tooltips as expected. However, select an item in the list. and close the list. Try to open the list again and you app crashes. PLEASE tell us how to fix this.
