Have you noticed if this happens primarily when you have it plugged in via USB? Mine does all sorts of strange things with the cable attached - its well behaved when unplugged.
Was the item fully charged before use? Was it plugged in via usb while this happened?
I would say try to erase and deregister the item? If not can always attempt a Factory Reset
With the Nook turned off
Hold the Power, Home Button and Vol + Button until the Nook powers on
A Reset Dialog will appear Power to Exit and Home to continue
Wait a few moments and it will reset to fresh.
Reregister the device as you would when you first turned it on.
Something I do with my Ipod once every few months is Factory Reset when it locks up or gets jumpy. It might work with Jumpy Nook.
I had my NC for 5 days before something similar happened yesterday. I pressed the home button and the user guide opened and started flipping pages. I turned it off as soon as the page flipping stopped. When I turned it back on, there was no more page flipping. I'm wondering if temperature change might have been the culprit as it had been in a cold car for a 30 minute drive.
The 14 day return policy is for money back. If the device does not work properly, you can coontact B&N (if ordered online) at their customer support number, and they will send a replacement. If purchased at a store, they will replace it at the store.
Thanks. I had also realized that the policy is 14 days from date received..so technically I was still within the window. I went to the store today and the Manager exchanged it with no problem. The kid selling them told me they have had a few folks come in with the same issue. However, in those cases he claimed that it was that the screen was dirty and the finger prints were causing the issue (mine was clean). Another case they said the case the book was in had a magnet that was messing with the unit.
this is posted elsewhere, too.
Clean the screen, power off, then back on, and see how it works. I ran across that solution a few weeks ago and it really worked.
