Dear Forum,
The restriction was caused by internet explorer.
I did not run internet explorer to begin with and immediately installed Opera. After messing around with program defaults and uninstalling Opera I have got links to open in IE. I don't like this but it works.
This link helped:-

I got it working in IE and then tried to install Opera and got the restrictions problem again. Could this be Microsoft messing around? Have had to uninstall Opera again and use IE.
Anyway thanks for your help.
Hope you are keeping well,
All the Best,
Bill Z
