I get similar problems. I'm using ZA pro 3.7.159 and the true vector engine will lock up and or crash. What happens is I will be browsing the web and all of a sudden TVE will consume 90+% CPU and the site freezes. I have to then close ZA and restart it. It has got better when I upgraded to the 159 build as it seems to only happen a few times a week now. Before it was several times a day. ZA seems to be getting worse
