title: Calendar appearing again after changing tabs or minimizing browser
body: <p>I'm using <a href="http://amsul.ca/pickadate.js/" rel="nofollow">pickadate</a> jquery plugin and applying it to a field in a form page.</p>
  
  <p>When the user clicks on the input field, there are 2 possible options I'm dealing with:</p>
  
  <ol>
  <li>the calendar appears and the user selects a date (after that the calender automatically closes)</li>
  <li>the user just close the calendar (selecting no dates)</li>
  </ol>
  
  <p>What's happening is that after one of the 2 options above, if the user opens another tab in the browser (and then go back to the form tab) or minimize the browser (and then open it again in form tab), the calender shows up again.</p>
  
  <p>This only happens if the last field selected is the one with the pickadate plugin applied to. If the user selects another field that does not contain the pickadate plugin and does that same process (of changing tabs or minimizing browser), the calender doesn't appear again.</p>
  
  <p>What should I do to does not make the calender appear if the last field select is the one with the pickadate plugin applied to?</p>
  
  <p>The code that calls the plugin is:</p>
  
  <pre><code>$(document).ready(function() {
      $('.datepicker').pickadate();
  });
  </code></pre>
