Is she using yahoo.com or yahoo.co.uk in both attempts? I

have a yahoo.com address but can't log-in on the yahoo.co.uk page - only works on the .com site.

She is using her .com address ....which she tells me is the only one she has.Thanks for the thoughts.

I have a yahoo.com address. I find I can access it via Y.co.uk and even .au - it doesn't seem to matter what yahoo site I am in.

So, can't help at all - sorry.
