Disaster Averted!
Thanks one and all for your help and suggestions. My dilemma was resolved when I went out to see 'Bullet Proof Monk' at the cinema tonight. Shaggy, of Cockney Commandos fame, came to pick me up and when I started to explain my problem he just twisted the bloody thing off before I even finished my sentence. His Kung fu skills are still strong and I obviously need to practice more. Top film by the way!
