Possibly the buggiest software I have ever used.
I just started using Carrara a week ago, and this is possibly the most unreliable app I have ever used.
It seems as if I have to save a model as a new file every time I make a change, or I will lose it. I can save a file, close Carrara, open Carrara, and none of my changes is there. Further, Carrara will simply stop working about every 20 minutes, and has to be quit and restarted.
I realize that this is supposed to be Carrara 8, but it seems like Carrara beta.
