YOU HAVE DONE IT!!
That was it....I needed to click on move selected pixels.
This is like learning a new language.
Thank you.
You have no need to apologise, it's me, for some reason I wasn't seeing it until this line of yours...
[Emphasis added]I've said this once before, let's hope I mean it this time: I think I may know what you mean.
The blue box indicates an active selection where manipulation only applies to the selection, not the pixels within the selection. You will want to use the Move Pixels tool ( ) instead of the Move Selection tool ( ) to adjust the selection. Now the pixels the selection is composed of will be effected, i.e. the image.
That should be it.
