Indeed, I do like to learn things.... but that is not why I argue with you. -- Cheers, John. /=================================================================\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \=================================================================/
