title: How do I use Watir::Waiter::wait_until to force Firefox to wait?
body: <p>I have some buttons that get disabled when adding a user.<br/>
  What I need to be able to do is have firewatir <code>wait_until</code> something is present.<br/>
  I am trying to use this right now:</p>
  
  <pre><code>count = 10
  while count &gt; 0
  browser.button(:name, "_eventId_addEmployee").click
  Watir::Wait.wait_until_present {text.exist? newHireUsername}
  end
  count -= 1
  end
  </code></pre>
  
  <p>For some reason I can't get the <code>wait_until</code> method to work correctly.</p>
  
  <p>Thanks in advance!</p>
