if I delete a playlist which contains a playlist which contains tracks, the playlist moves to Unattached Items. If I delete the playlist from Unattached Items, the tracks which were in it now appear there.

This is how mine has always worked, for every version of software from 1.0 to 1.02RC. I always assumed that was what it was supposed to do.

The workaround is to just pretend that that Unattached Items listing on your emplode screen is not really in bold print, and then deal with it the next time you do a synch. :-)
