It happened rather frequently. At first I thought it was due to a script running (or not) but then I thought it couldn't be, it had to be something local. Usually waiting cleared it, but once or twice I had to kill Firefox. I had run several versions of Ubuntu previously on the same kit with no problems. Then I upgraded my machine: I've now got a 64 bit laptop with 4G of RAM running 9.10 and have not seen the problem at all, so I guess it was something to do with the former machine. Yes, it is frightening, you think your machine is being hijacked or something. But I don't think there is anything like that happening, just some internal issue over resources. Ollie K </div></div>
