title: `INSERT` is only inserting a single row
body: <p>I've been happily using SequelPro in place of phpMyAdmin to access my local database.</p>
  
  <p>I've inserted hundreds of rows into some tables without a glitch.</p>
  
  <p>Now I can't insert more than a single row into any table - even using the same INSERT script I previously used successfully. I CAN use the same script to insert multiple rows via phpMyAdmin, however. Via SequelPro only the last row is entered:</p>
  
  <pre><code>insert into country (country_desc, country_pop) values ('Monaco', NULL);
  insert into country (country_desc, country_pop) values ('Mongolia', NULL);
  insert into country (country_desc, country_pop) values ('Montenegro', NULL);
  insert into country (country_desc, country_pop) values ('Montserrat', NULL);
  </code></pre>
  
  <p>...though i think my tests have shown it isn't the script at fault. (The country table has an auto_increment column, country_id, which is working fine for the single row inserted.) </p>
  
  <p>I've tried restarting Sequel Pro and my local server MAMP but no joy. It feels like I've changed a setting in Sequel Pro unwittingly. </p>
  
  <p>Has anyone seen this before?</p>
