Hi - I use a mSD card to boot into CMD7 on my Nook Color. Pretty often when I'm playing a space hogging game my device will freeze. So I need to reboot. Only when I try to reboot it takes 4 or 5 tries to get a successful boot. It will sometimes get stuck with the circle going around the poor little robot. Often it gets to my home screen, load 1/2 the widgets and freezes again. Does anyone know what' going on?
