Went upstairs, swore at the little Dell..... Hard reset.... different black screen appears restoring, previous versions and a mere ten minutes minutes later we were back at W7 , exactly the same as yesterday......
I would like to take this sincere opportunity to thank all of you for your advise..... and *&^% The automatic update.........from William...
On another point, It was not Pastel, The English Ho informs me that she uses the lastest version of Sage!
