1.3.1 still crashes when selecting city levels

Great graphics but still crashes alot version 1.3.1 still crashes when selecting the city levels but also crashes during gameplay for no aparent reason. It even froze up my computer one time. I have only played a couple of hours and it has crashed 5 times already. Great game loved the original but this one would be great if it did not crash. Being able to use the iphone as a controler works well love it.
