No - I'm OKing.

Yes.

I tried again fives times with OK and could.

Chris,

When you say Shift-Enter, do you mean that MM opens the Properties dialog for the selected track, and that after cancelling out of the Properties dialog focus doesn't revert to Now Playing?

I tried this, but couldn't reproduce.

Edit: 1 Click Track List track
2 In floating Now Playing, click track and press SHIFT+ENTER
3 Click OK

Expected: Now Playing retains focus
Observed: Now Playing loses focus to Track List

EDIT: Note: Likewise with Tree rather than Track List.
