jquery tipsy not firing onclick IE
<p>Hi I am using the jquery tipsy plugin to display colour names above colour swatch images.</p>

<p>I am trying to trigger a checkbox to be checked/unchecked when a user clicks on the image.</p>

<pre><code>$(document).ready(function(){
     $('.label_check_colour').click(function(){
        setupLabelColour();
     });
}

function setupLabelColour() {
     if ($('.label_check_colour input').length) {
          $('.label_check_colour').each(function(){ 
              $(this).removeClass('c_on');
          });
$('.label_check_colour input:checked').each(function(){ 
    $(this).parent('label').addClass('c_on');
        });                
    };
};
</code></pre>

<p>HTML</p>

<pre><code>&lt;div class="selectableSwatch"&gt;
      &lt;label class="label_check_colour" for="colour_1"&gt;&lt;input type="checkbox" id="colour_1" name="colour_id[]" value="1" /&gt;&lt;img class="colour_tip_1" width="20" src="img/colour-palette/1" /&gt;&lt;/label&gt;
&lt;/div&gt;
</code></pre>

<p>Everything works great in Firefox and Safari but not in IE8.</p>

<p>Help...please.</p>
