Normal
Ripping a CD. Most time it is ok, but for example when it starts to rip a track it slows down the system for a short time and appears as not responding and then it ok again. I had it even totally srewing up my system when it was ripping a very scratchy CD and blocked my DVD drive so it wasn't opening and I had to wait till it finished ripping - which took about an hour. Since it was not responding all the time I wasn't even able to stop ripping. Tried that on two machines and had the same experience.
