Now used the Fix-disk package that I installed .
Very grateful for all advice regarding the problems here. Thanks for patience with us non tech people.Don't want to bang on about any disability, but please forgive me when I have missed some information that was visible ( such as: on Web-If, the current versions (custom and otherwise) are displayed in the bottom right-hand corner) etc. I an, also, visually impaired and using specialised magnification on my PC, the downfall being that I do not see the whole screen in one go. All good again anyway and many thanks.
