Something strange is going on with my itunes and I'm wondering if someone can help me figure out what the issue is. For some reason, it keeps on wanting to download certain apps, namely MobileNavigator North America (Navigon 1.3) which I already have ... including the traffic update. I can clearly see the file on my hard drive with all of my other apps (itunes/mobile applications). It looks like it's just in some sort of loop and wants to download it again. I have gone in and deleted the semi-downloaded app in the "downloads" folder, but every few days it keeps trying to download it. Any ideas as to how I can get this to stop??
