Drupal 7 disable overlay
Drupal 7 eases Request Response scenario by using a AJAX module known as Overlay which is included in core drupal package. But due to slowing of experience due to longer load time one may need to remove that. To diasable the overlay module in drupal 7 you have to go to Modules -> Overlayuncheck the Overlay module box and save it. Now pages will load much faster as per my experience !! Happy drupalling !
