title: jQuery click events not always firing
body: <p>We have several buttons and checkboxes that have jQuery click events defined for them in document.ready that perform ajax callbacks. On our test server they always work correctly in all major browsers (IE, FF, Safari, and Chrome). We log enough information on the server to determine that they're firing correctly.</p>
  
  <p>However, on very rare occasions we've found in production that they're apparently not firing at all for a few random users, but we can't come close to reproducing this problem ourselves.</p>
  
  <p>We know that Javascript is enabled for these users. We've seen the problem with both IE8 and Safari, but it hasn't occurred enough times to definitely correlate it to a specific browser/version.</p>
  
  <p>We're currently using jQuery version 1.6.2.</p>
  
  <p>Any ideas on what might be causing this problem? </p>
