I just responded to an identical post in the dev forums, which I assume was yours <https://devforums.apple.com/message/783296#783296>: See the last paragraph from Text System Storage Layer Overview: Tracking the Size of a Text View: https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/TextStorageLayer/Tasks/TrackingSize.html > Note that a text view can be resized based on its text container, and a text > container can resize itself based on its text view. If you set both objects > up to resize automatically in the same dimension, your application can get > trapped in an infinite loop. When text is added to the text container, the > text view is resized to fit the area actually used for text; this causes the > text container to resize itself and relay its text, which causes the text > view to resize itself again, and so on ad infinitum. Each type of size > tracking has its proper uses; be sure to use only one for either dimension.
