Hi Can anyone suggest a possible solution to why I'm having an error with SciTE 'DragDropEvent.au3 requires version 3.3.8.0 at least I'm on the latest SciTE4AutoIt3.exe which has been downloaded ,installed and uninstalled a number of times today. But I'm still getting this annoying message... I'm trying to get this simple example working which was included with UDF..   What could I be doing wrong..? BTW DragDropEvent.au3 is in the "C:\Program Files (x86)\AutoIt3\Include\" folder..
