@Butain,
Hey Butain - I'll give Dutchy a shout - he'll know the answer - he's still awake in his opposite end of the world - PaddyBoy may be along in a bit too.
I don't do crosswords - so haven't a clue if it would be right - scratcher is just.... one of those words that makes me laugh a bit!!!!!!!!!!!!!
I thump my laptop regularly - it even answers me back at times!!!!! Ha!
Good Luck
