I just saw the Live plugin doing Ajax requests on the "Add new Goal" page. I suspect this is an unwanted behaviour that was introduced when we started merging assets.
There should be a way to activate those requests only when the live widget is really shown.
What version are you using? This should already be fixed in trunk.
Let me know if this is still a problem.
(In ) refs #1662 - add appendTo setting so we can attach spy to the #content div; previously it would attach to the <body> and continue to run in the background after the widget was no longer present
