Really. The only time I had a problem, I upgraded my video drivers and it fixed everyting. It's a bit power hungry for video features. I've found it to be more stable than Poser on larger scenes and less quirky. I did have problems in the beginning though, but as the updates keep coming out, it continues to get more stable. (That is why they still call it Beta though). I hope you have better luck trying it in the future, because it is very capable software.
