I also noticed that Vue7 is much more aggressive than Vue6 in what concerns CPU usage. With Vue6, I could be rendering and still use other apps perfectly well. But with Vue7 is not quite like this. Sometimes, Vue7 seems so hungry for CPU, and its process seems to have such a high level of priority in the system, that working in other apps become sluggish.
