@CD001 RE: "You simply need to ran an ATI graphics card........."
Well, actually, now you come to mention it I did have one crash with one of our machines - I had mercifully forgotten it. I downloaded and installed (you guessed it) the latest driver update from ATI on the lappie I use as my test-bed for such things. It keeled over during boot-up as a result of that shite. Didn't in practice matter given that I had run back-up first but it was a touch irritating. -:)
