Hi, all: Currently using it, after having some surfing slowdown (IE7) with Sandboxie/ DefenseWall. I found ZAFF did not slowdown surfing speed, and apparently is an app of " more than a sandbox " . ZAFF may not have a lot of functionalities, but it just requires a little, or virtually none users interactions. Therefore, it is very quite and resource-light. And working harmony with GeSWall 2.38. So far so good.
