This function is called periodically via the Event Loop.
Are you trying to run your own event loop, and call this method every so often from it to update a progress bar or something, because your application is doing something that takes a while?
If so, then you’re fighting the framework as we say in the Cocoa world. A good indication that you’re doing so is that you’re sending - setViewsNeedDisplay: and -display to an NSWindow.
You should be using an NSOperationQueue or an NSThread to perform your long-running operation. Let Cocoa manage the main run loop (event loop) from the main thread like it normally would. To update your progress window, just just post progress information back to the main thread from your background operations or thread.
