Disk11,

Interesting, I am running Knoppix v3.3, used to run it through the CD, but for more than four months now, been running on a hard drive install...

But, I have always used a Ps/2 mouse, for more than six months now, first five months was a Microsoft Optical Explorer (wheel) mouse, and now, my old one was going "flakey", and is a "no name" brand, wheel optical mouse - both work fine. The problem I was having with my old mouse, causing me to replace it, was it would skip across the screen, and usually click on my KMenu, even though I didn't move the mouse physically. (I think the optical was going out on it)

Once replaced, no more problems again. Don't know what to say, I have heard people with problems on a USB mouse, and very few on PS/2 - but thats me.

Hope this helps,
Cuddles
