Many thanks for sending those. I tried to PM you but I'm a new user and have to be "5 greater" or something I received a patch to fix this problem (from Longmans) before I saw your post so I never got chance to try yours. I've uploaded the fixes I was sent for Exploring Science 7,8 and 9.
Thanks again,
