It's just a minor thing, maybe even by design .

When you put up track details and leave it there until the next song jumps in, the info isn't updated. I would like it to do so, since the "About" screen does this already. Try it, I think it's fantastic! Boot the player, quickly navigate to the "About" menu, manually scroll it to the network info and leave it there. When it obtains an IP address the info is updated! Absolutely slick! Oh, unplug ethernet and let it obtain an uPnP address, cause you have to be really fast with ethernet attached while booting!

Again, I don't think it is a major issue, it's just something cosmetic and it would just be nice to have it dynamically updated.
