CI2 - Is there an issue with loading libs?

[eluser]stormbytes[/eluser]
Just upgraded to CI2 - latest build.

Well.. Made the required changes to model name conventions, etc. So far looks just fine.

Here's a caveat -

It doesn't want to load my own libs. I created a class called MY_common.php (code below).

I'm trying to load it via $this->load->library('common'); and it won't take it.

I also tried autoload, same deal.

Uhm.. Clues?
filename: MY_common.php

Code:

<?php

if (! defined('BASEPATH')) exit('No direct script access');

class MY_common extends Controller
{

    function __construct()
    {
        parent::Controller();
        
        $data = array(
        
            'arrow_doc_title'       =>  $this->config->item('doc_title')
        
            );
        
        $this->load->vars($data);
    }
    
    function index()
    {
        
    }

}

Code:

An Error Was Encountered

Unable to load the requested class: Common
