Levanah - Go to geekatplay.com and do the tutorials, especially intro ones. There are a number pn Vue 11.  I don't know what version they refer to, but they would be helpful no matter what version. This should make Vue a lot easier. Don't go back to Poser. If you stick with Vue, I believe you will be happy. Give yourself time.

As to stability, my Vue 11 Infinite is the most stable I have used. It also seems the smoothest when running.
