Hi norcalmommy,
I did a little bit of tinkering with LR this morning and just want to clarify -
Is it possible you imported a .cat file, so that when you went to the PLAYBACK screen you were viewing Categories rather than Playlists? The Save and Save As buttons only appear when viewing Playlists (as only Playlists are able to invoke customised playback settings).
However, even when doing so, I clicked on the HOME icon and then clicked back to the PLAYBACK screen and I remained under the Category list (thus the SAVE/SAVE AS buttons still had not returned), so I'm wondering whether this is the same thing you're experiencing.
Rest assured we'll get to the bottom of this though!
Cheers,
Shuki
