Hi BR549
Thanks for the reply, I had a reply from tweakie on this question but on another board:
Under 'Config / General Config' check the box 'E-Stop the system' on 'Pgm End or M30...'
Then make sure your programs all end with M30 (most do anyway).
Tweakie.
It works a treat but I do take on board your comment regarding loosing any references,
maybe when I use this function I should do a ref all at the start as well
