Thanks for the info.
Like many people, I avoid the home screen, don't use shelves, and don't connect to the internet or PC with a side-loaded book open. This has avoided most of the glitches that 1.2 is supposed to fix.
Don't like hearing about TOC problems or the black bar. I use a solid black screensaver and turn off wifi when I go through airport security with my Nook. It looks more "turned-off" with an all black screen than with a default screen. The black bar might prompt a strategy change.
