It sounds like this is an issue with the Nook Touch. There's a thread about it here:
http://forum.xda-developers.com/show....php?t=1467429
The issue they describe in this thread sounds pretty much exactly like what my NT is doing.
I've checked out the files listed and all but one of them exist on my NT in the same locations. I'm not sure if the fix they're discussing here would work on my Tablet or not but I may give it a try.
