Ken,
I am a relative newcomer to Vegas, but from what I am told, many people thought that it was a far better NLE back when it was owned by Sonic Foundry. There has been some disgruntlement since it was taken over by Sony, but Sony recently announced that they would be trying to make it a 'truly professional' NLE, and would be trying to take over the market. We'll see. I had a lot of problems with 9.0a, b and c (and missed d). 9.0e for me is very solid. I am sorry to hear that you are not having as happy an experience.
A lot of people find that hardware has a lot to say about whether Vegas is stable, or not. The consensus seems to be that if you get Intel-standard everything, you cannot lose; and if you veer from that, you are taking your chances.
If I may ask, what is your hardware config? And who manufactures your parts? And are you running x32 or x64?
