Can't get "Track outgoing links" functionality to work

First of all, I'm guessing that this is something I'm doing wrong as opposed to there being a problem with the code. See below for the steps I've taken to investigate the problem - I'm now stuck and don't know where to go next. If anyone could point me in the right direction as to how to continue investigating this problem, then I'd be very grateful.

I've been trying to track external link clicks as events but am not having any luck. The /admin/settings/googleanalytics screen is configured thus:

• Google analytics account number is correct (normal page hits are being tracked, no problem)
• Users cannot control whether they are tracked or not
• All roles selected for tracking (this is not my normal configuration, but I thought it would aid debugging to check all these)
• Add to every page except the listed pages. (admin, admin/*, user/*/*, node/add*, node/*/*)
• No segmentation information selected
• All "Link tracking settings" checkboxes checked
• Latest (ga.js) tracking code
• I have tried selecting both "header" and "footer" in the Javascript code select list

My knowledge of JQuery is non-existant (I'm currently trying to learn) but need to get the event tracking switched on sooner rather than later. When I refresh the page and set a breakpoint in the javascript using Venkman, I see that Drupal.gaTrackerAttach = function(context) { is entered and context = context || document; is reached. After that, no breakpoints I set within $('a', context).click( function() { are reached.

By the looks of the code, the a tags in the page are altered dynamically. I have tried looking at the HTTP headers using HttpFox but can't see any HTTP requests that look like they are tracking the outgoing link that I am clicking.

Thanks in advance for your help,

Steve
