I can quite understand how you feel about poser 7 letting you down in some way or another but calm down jugoth, there are obviously some bugs and problems with it  right now and these will almost certainly be sorted out in a future service release.
As somebody suggested in another thread a week or so ago, why not use Poser 7 to get a feel of what it does and to familiarise yourself with it but stay with poser 5 or 6 to do your main work until an SR1 for poser 7 arrives that's what I am doing.
