Now I've enabled `projects` how do I stop the pop up?

So I've edited the settings.js file and enabled projects.

Now EVERY TIME I go to the EDIT screen I, get the/a pop up asking me if I want to start a project.

How do I get rid of it for good?

If I want to start a project, I see there is a new button (top right) of the edit screen hidden with the debug, etc buttons.

Does that happen even if you are running an active project?

It only happens when I log in with a new session.

To re-phrase that:
I power on, load the browser and go to one of the 3 machines I've updated.
I see it on the INITIAL loading of the EDIT screen.
