And that's not the worst story, every 1 minute or so, it starts saying "parsing the solution" or "update intellisense & browsing..." then the whole program hang for a while... how can we work with such a half-baked product like this?

If you are using DevExpress it may be their Unit Test Runner bits causing the slowdown. Disabling it seems to fix the problem. I'd look at any other extensions you have installed to see if they may be contributing.
