Thanks so much for your time and help, John.
I'll give it a shot on Vista. I don't have access to my daughter's XP machine right now - she took it with her and will be back tomorrow. So if this doesn't work, then I'll try it on her machine tomorrow.
I cannot believe this has literally taken up my whole day and night - I'm glad we had a Nor-easter here today as I had no intentions of going out anyway!!!
Thanks again - and I'll let you know if it works on Vista.
