I am find this strange behavior, when I copy a page and then change the markup and content in it, the original page it was copied from also is changed simultaneously. There should be as far as I know any link between the two. If I then change the original, the copy reflects the changes made to the original. I even tried created a new blank page and then copying the mark up, the page that the mark up was copied from changes if I edit the new page. It's maddening. Is this a setting in Sharepoint Designer or a bug in 2007? Has anyone else experienced this, and if so, how can it be resolved?
