Homepwner process doesn't stop - XCode 4.4


I have installed XCode 4.4 from the app store and at the end of chapter 11, when command+Q sometimes the process doesn’t stop. Ive tested and tested and sometimes it happens and sometimes not. I get a “terminating in response to SpringBoards termination” in the output which i havent noticed before working through these chapters. Anyone else experiencing issues with Mountain Lion and Xcode 4.4? thanks


As an example. I will run the app and press the “New” button x number of times, adding a bunch of possessions. I can quit the app and it will terminate fine and other times i will quit but the process is still running and I have to go to the terminal and kill it.
