 * Hello,
 * On the Media Library Folder page I get the error “Javascript error : Uncaught
   TypeError: this._addClass is not a function”. Not sure how this affect the functionality
   yet, but I guess this message should not be there in the first place. Please 
   advise.
 * Kind regards, Eric

 * If you can go to the Media Library Folders Support page on your site, to the 
   System Information tab, there you can hightlight, copy and page the information
   about your site’s configuration and send it to us at support at maxfoundry.com
   then I’ll review it.
