I hate to deluge this forum with my questions, but BONES is driving me crazy. The problems are so erratic, and so varied that I don't quite know where to begin. I know that it's a poor craftsman who blames his tools...but...is BONES unstable in Carrara 2.0? Am I simply letting myself in for major headaches here?

I fully intend to upgrade to 4.0. Is BONES any better in 4.0? If it is, I'll deal with other parts of the animation and deal with flying birds and such at a later date.
