Best to put all your questions on one thread. People also appreciate acknowledgement of their answers, that way you always find them willing to help you again.
Very thanks for all the help yesterday.
Particularly Captain2, scorpiojo, mazie (and thanks for the tip), baldric and bibblebub. My sanity is now thankfully restored..!!
I have one question left:-
Said to be used by Indian dentists? (5)
I think it my be TIPIS but don't quite get a dental connection. Can anyone help please?
