title: New version of PHPMyAdmin has stopped me being able to edit data
body: <p>PHPMyAdmin has just been upgraded by my server admin to v4.0.4.2.</p>
  <p>Now I am unable to edit rows in the following table:</p>
  <pre><code>CREATE TABLE IF NOT EXISTS `product_options` (
    `product_id` int(10) NOT NULL,
    `option_id` int(10) NOT NULL,
    KEY `product_id` (`product_id`,`option_id`)
  )
  </code></pre>
  <p>PHPMyAdmin just returns this error message when I browse data in the table:</p>
  <p><code>This table does not contain a unique column. Grid edit, checkbox, Edit, Copy and Delete features are not available.</code></p>
  <p>I don't want a unique column in this table, so how can I edit data?  Is there a setting I can change?</p>
  <p>Many thanks</p>
