I just purchased a MBP and received a free 4GB Nano. Since the Nano doesn't come with a wall charger, I have to use the USB port on my computer. When I plug the Nano in, the screen darkens. This makes it very hard to see if the Nano is charging and/or if its completed the charge. Is there a way to temporarily brighten the screen?

ALSO, when I plug the Nano in via USB with Windows, it automatically mounts the Nano as a drive. Is there a way to turn this off? I read that this can be done in iTunes, but I use MediaMonkey in Windows.
