I always close using the standard red X button on the window interface. That's the way I've always done it before an upgrade. And, I've never noticed any Calibre related process running after closing the gui. I don't have mine setup as a server.
In any case, I can't see how the gui config file would be corrupted when the gui has been closed. Heck, maybe I did do something wrong, that's why I didn't post the problem myself. I thought it was just a fluke or something I did. But, now I see someone else report the exact same problem after 6.47 came out. I'm also on Windows 7 x64, but, I'm not sure that's a factor.
