Oh my goodness, Andere, I have only just found this post from you - over three months old. I must seem very ill-mannered to just leave you in mid-air after you offered advice, but I never returned to look.
But it must have been someone else who said they had Windows 8 or 8.1. I only updated to Windows 7 about 18 months ago and I took long enough to find my way round it.
So I don't know why I started getting messages to install IE 11, and they still appear now and again so I delete and carry on. Not ideal really.
Anyway thank you very belatedly, and sorry.
