I've noticed that V9 crashes more often than V8, but it's nowhere near being frequent enough to damage playability. And although I mean no offense to Badspot's work, there are a few bugs that cause minor annoyance. But, the amount of the good introduced in V9 far outweighs the bad.
In short, contribute by politely reporting bugs instead of getting angry, and Badspot can fix it all up when he get's around to it.
