Just to add, when I'm first adding the items, I can go in and out of them to edit. WHen I click edit, it opens as a pop up. When I have published and then create a new revision to edit is when I run in to the problem. At this stage, clicking edit opens the window in that tab, not as a pop up.
Hi Jo,
I have now fixed this problem - it seemed to be that when there was an apostrophe in a link title it failed to open in the popup, and so editing it failed.
Thanks
Joe
