 * I just wrote a new widget, but it is not working. I have written a bunch of widgets,
   but this one does not work and I cannot figure out why. The widget is part of
   a custom theme I am working on. The theme itself works fine, as do the other 
   widgets I wrote with this theme. I wanted to add an additional widget to the 
   theme. What happens is this:
 * The new theme installs and activates properly — no errors.
 * The new widget shows up on the widgets page, so far so good.
 * I drag the widget to a side bar, that works just fine.
 * I set the widgets parameters and then click save. That *seems* to work.
 * I visit the site. The site displays fine, but the widget does not.
 * (head scratching, hair pulling…)
 * Using Firebug I discover something odd. The POST for this new widget has widget_number
   set to -1. *NONE OF THE OTHER WIDGETS* have this setting. Also, there is no RESPONSE—
   all other widgets have a RESPONSE from admin_ajax.php. WHAT IS GOING ON HERE?
 * Here is the code:
 *     ```
       class Deepwoods_GoogleAdSense extends WP_Widget {
           function __construct() {
             /* Widget settings. */
             $widget_ops = array( 'classname' => 'dwsgoogleadsense',
       			   'description' =>
       				__('Display Google Ad Sense Blocks',
       					'deepwoods') );
             $control_ops = array( 'width' => 300, 'height' => 350,
       			    'id_base' => 'deepwoods-adsense');
             /* Create the widget. */
             $this->WP_Widget( 'dwsgoogleadsense',

 * What am I missing? I have been staring at the code for some time and I am not
   seeing an error. Maybe a fresh set of eyeballs will spot some silly mistake.
