I started with one library being used for both my Windows account and my son's. But I got tired of sorting through all the music he downloaded, so I moved all of his music to a new folder under Public (NOT under public\music). When logged into his Windows account, Zune software is monitoring his folder and mine, and he sees everything, which is great. But when I'm logged into my account, Zune software *says* that it's only monitoring my folder (public\music) and not his (public\son), yet his music continues to appear in my collection. Worse, when I manually delete his songs from my collection (but not from the computer), they reappear next time I start up the software.
Is it possible to have different collections on the same PC, when using different Windows logins, but the same LiveID?
