I remember exactly the same behaviour on XP when I started using computers in 2003. At the time I thought the machine had been compromised, and you might think so with the mouse pointer jumping all over the place, and opening a multitude of windows at the same time. Mind you the blurb did say that the mouse was not for XP, but did appear to work in some sort of default mode without having to install the drivers from the floppy. Also I was using a kvm switch, which is as good as a ps2 ext on mouse and keyboard, so may have been related to the "mouse with a mind of it's own" problem. > > There's another thing to point the finger at: How Linux handles > keyboards and mice.

As I've just started using the new A4tech that I had as an instant replacement for one that went down the tubes. It's always nice to a new one instantly available, rather than having to wait for snail mail to deliver it. > > I do wish keyboard navigation worked better in Linux.

In my case, I just need to learn how to use the keyboard more effectively, without having to rely on point and click. 17:57 pm, sky blue with some red on the clouds (good sign I believe for tomorrow) .
