PPS I've tried the Juke-Box trick described above on my laptop, and BIAB hangs on the eight song again, but this time it plays the whole song first. Various odd things happened to my desktop after my Juke-Box runs - I opened a document with Open Office Writer, and it behaved strangely, with lower case "s" replaced by a newline, and when I plugged in my iPod I was informed that iTunes was missing essential files and that I'd have to reinstall it.

The lower case "s" problem disappeared after a reboot, but iTunes still complained.

I'm concerned that there is a rather nasty bug lurking in BIAB, which causes it to overwrite system information in some way.
