I have a 10 day old Nook Color (actually a replacement for a previous Nook Color that was defective), and it seems to be "stuck" on FaceBook. Every other function of the device works, except the internet. I cannot change the url, I cannot go to another site, it's....stuck. This Nook belongs to my husband, and he is VERY fond of it. In fact, he doesn't even know that it's not working properly... again. I have had it on the charger all morning, and it has not helped. Any suggestions are GREATLY appreciated.
