How can I get selenium/cucumber to interact with a "hidden" link that is now in a lightbox/colorbox?

I'm using the colorbox library to display lightboxes within my application (http://colorpowered.com/colorbox/). The code seems to work fine in the browser, but I'm having trouble getting the automated test to work.

Here is some inline HTML that gets generated:

<div class='hidden'>
  <div id='override'>
    Are you sure you want to override this action?
    <br>
      <a href="" class="close_colorbox">Cancel</a></li>
      <a href="#" onclick="override(this); return false;">Override once</a>
  </div>
</div>

This is the javascript that opens the colorbox:

$.fn.colorbox({innerWidth:600, inline:true, href:'#override', scrolling:false});

That code opens the lightbox and display the contents of my '#override' div. In my cucumber tests I can find text from inside that div, but I get an error if I try to follow a link:

  When I follow "link that generates override"    
  Then I should see "Are you sure you want to override this action?" within "#cboxContent"
  Then I should see "Cancel" within "#cboxContent"
  # Then show me the page
  When I follow "Cancel" within "#cboxContent"

Gives this error:

Has anyone seen this error before and how did you get around it? (If I uncomment the 'show me the page' step then it also works)

I am having a similar issue with the Jquery-mobile framework.

From what I understand, Capybara is supposed to wait until all the AJAX calls are completed before doing a check or moving on. However, if you are having an issue where you think the page isn't finished loading you could try adding a simple "sleep 1" to Capybara's stock "I press" step to see if that helps.
