Is there anyway to keep blank apps from opening up when you touch them on your springboard? Sometimes I accidentally open one on my springboard and I get stuck on that screen. Sometimes I can get out of it when I hold the home button but sometimes I cant. When I cant get out of it I have to shut the iPod off. And many times when I try to turn on my iPod after turning it off, it doesnt repond. So its a real pain.
