It is animating a progress indicator. I have encountered my own problems with this heartbeat thread deadlocking Cocoa. (You are not encountering a deadlock, per se.) You can try removing the progress indicator from your UI, turn off its animation, or configure it to not use threaded animation (set the usesThreadedAnimation property to false; you can do this in IB via user attributes).
