I think this may have something to do with certain viewers not honouring the readonly flag. When I open in some viewers I am able to move the annotation, and in others I am not.

We usually try to mimic Adobe Acrobats functionality when it comes to things like this, and when opening the document in that viewer, you cannot move or edit the annotation.

Thanks!
