Case sensitive library name?

[eluser]-sek[/eluser]

Code:

$this->load->library('CiGoogleMapAPI');

works

$this->load->library('Cigooglemapapi');

says

An Error Was Encountered

Unable to load the requested class: cigooglemapapi

According to http://ellislab.com/codeigniter/user-gui...aries.html CI docs say "You can submit the file name capitalized or lower case. CodeIgniter doesn't care."

Any ideas?
