[Enraptured]

For the past few months or so I've been having problems with my Nook Touch whenever the wi-fi is on. At first the problem was minimal - it would lock up for a few seconds every few page turns. But now it's at the point where if I leave the wi-fi on for more than a couple of minutes, the reader has to be restarted. Nothing about my internet connection has changed, so I figure it has to be the device itself. Could it be the related to the amount of books I have on the Nook? The memory is almost entirely full.

Does anyone else have this problem? Anyone know of a way to fix it? It's at the point now where buying a book from a different store and manually transferring it is less hassle than buying the book from B&N, which is just silly.
