A real processor hogging app which has a minor problem. Due to the way it works it needs to constantly refresh its display but as a side effect it seems to refresh more than its own list of processed files list. My taskbar and open windows are like the Blackpool illuminations at times when it is running.
Can't say I've noticed that. Since it needs to log out and back to complete its cleaning I normally have most things S/D. On CPU/memory has a little burst of 40% useage in my setup - about the same as refreshing this page.
