Thank you Albert.
There was another problem that may well be associated with it and which may well be linked. I am sure that, in the past, I could block/select some text and then drag it to a new location. This also has disappeared.
I have to admit that my main use of Validator is for validation as I have used Hotdog for years and still do. But it is good to be able to do editing in H.V., especially if I am working one two different projects at once. Thank you for a great program.
Best wishes,
Chris.
