You sound absolutely right. I was indeed using a generic(old) page as a template (because it had my headers/titles etc.) and now that I have destoyed that and re-created it is as though there never was a problem.
If it's gone - it's gone, and although we are curious people who find these things very frustrating I am so grateful for your assistance that you pointed me in the right direction.
Thanks again - for sticking with me.
Best,
Gary
