The spinning wait cursor (see Figure 12-1) is displayed automatically by the window server when an application cannot handle all of the events it receives. If an application does not respond for about 2 to 4 seconds, the spinning wait cursor appears. You should try to avoid situations in your application in which the spinning wait cursor will be displayed. The Spin Control application provided with Xcode can help you eliminate code that is causing this cursor.
