I load M4... I notice it doesn't refresh (I am really starting to dislike the new library, sorry BB, I know you put a lot of work into it.)
So I refresh.
And every one I did has  << empty >> in it.
I've just LOADED M4 from it, so I know he's there. I checked the folder (moment of panic, there, believe me), yup, they are all there. (If your windows rattled near London... that would be because a huge weight dropped off me)
I loaded mats -- you guessed it. << empty >>
On restart they were back, but quite frankly... I've never had a problem with any version of Poser before, I can't send this one back as the return has expired by now, but if I had the option?
I'd actually ditch it this time round.
Nothing but hassle with it so far. Crashes like a sumbish, I actively HATE the library now, it's giving me so much grief.
Disappearing libraries which cannot be gotten back unless you restart Poser are just the icing on the cake.
The main header is still there, but the content listing goes to << empty >> and even a refresh doesn't work. (I loathe and detest that I have to refresh every time I install something new btw. Never had to do it with the old library.)

Quite honestly... I don't care if I lose the search. Give me the old library back. I didn't have to guess every time I wanted to do something. (And no, Search didn't find it either when it came up << empty >>)
This was after 5 minutes of having poser open, loading 1 (!!) figure and the elite morphs and textures. That's it. Nothing else open, nothing else running, nothing else in the scene.
WinVista Ultimate, 5gb RAM, Quadcore, 1gb Graphics RAM -- and I have trouble keeping the thing from crashing?
They gotta be kidding me.
