Ziggie,
Despite your 'oops' moment, I think you're right overall about the poor state of P7.  I have to admit that when I was installing it and found that even the 'install progress' bar didn't work, I started to get a bad feeling. (I mean, if they didn't take the trouble to fix something so glaringly obvious, what did it say about attention to detail?)

 I've been using the program for a few days now, and the feeling has only got worse.

Sometimes it's impossible to delete an item from a scene. Bad.
So far, I've had 3 or 4 total crashes. Bad - P6 never ever crashed on me.

I'm sure there are other problems, but these are the ones I keep hitting.  I guess it's back to P6 until the service release comes out, and this is definitely the last time I buy Poser as soon as it's released.
