I've just got a Nook Simple Touch, and I've got a couple of questions:

When I was charging/going through the setting screens I occasionally saw small horizonal white lines on the right hand of the screen, all the way down. I only saw this once or twice, but is this a sign of a possible fault? I haven't seen this when reading a book.

Also, is there any way of changing the order of the forward/backwards buttons? So the one that goes forward goes backwards etc.
