Yep, she wasn't floating back in my last trip to DL (Late June). I kind of prefer it that way. Don't get me wrong, I like DL's HM WAY better, but since WDW uses a rear projection, the floating effect looks much more convincing. I say until DL gets a rear projector Leota should stay on her stand. It just looks better.
Seriously, I actually prefer her not to be floating. I think the subtlety of the stationary crystal ball that you move around before you see anything supernatural works to a better effect, IMHO anyway.
