Sorry to be anal...but is there a security risk to a machine doing this? (I didn't see a FAQ...but I'm pretty dense.)
While I'm certainly not the definitave authority on this, there probabaly isn't a security issue related to this client. There is a heat issue however. Your CPU will be running at max when idle. This mean that you won't notice any speed problems doing your normal work, but the computer is going to be hammering itself at max. It's not inconceivable that you may hit a thermal problem if you have insufficient cpu cooling. -Mal
I have had F@H running for over a year. There is no security breach that I have ever noticed, and I have installed it on about 20 of the systems listed.
Sometimes I'll notice a slow response on a slower system. In that case right-click on the F@H tray icon and click on Configuration. Move the slide bar down to between 50% and 70%.
F@H uses a tight kernal that runs when System Idle is normally high. Some of the systems at work will be slow to respond so I throttle them down to get a better response.
