How to find out what's preventing a click from happening?

Question

I have the following link on the page:

<a href="/go/some/where.htm">...</a>

It lives among HTML that makes up a google.maps.InfoWindow box (which itself doesn't have a click event). This infobox comes up when the user moves the mouse over a mapping pin. For whatever reason, when the user clicks on a link in the infobox, it doesn't fire and I am trying to find out why.

The code base is huge and I have no idea where exactly the preventDefault or propagation is stopped. Is there an easier way? Can I hook into the event flow some way that would show me what is preventing the click?

In addition the JavaScript debugger that Wyatt mentioned, you can check the Event Listener on any DOM element in Chrome Developer Tools. Right-click the element > Inspect: Select the Event Listeners tab on the right.
