Use _blank to open a new page rather than _self.
Thanks very much.
That worked. However, when I place the new Edge file into Muse, it 'remembers' the old version and on publish has the same problem.
Any ideas? I've tried deleting the file, changing file names, but it doesn't seem to help!
It's like the code has somehow got stuck ... ?
Oh, great! Good luck on your project.
