Robby, you're a legend! That worked, thanks.
Now I start the Envisage and can capture stuff, great.. except now I have to learn the completely counter-intuitive user interface to figure out how to do it. A few pop-up hints wouldn't go astray.
Oh and a 4 second capture with the cap on gives the grainiest multi-colour image i've ever seen

Looking forward to this learning curve!
Anyway have a tutorial or a basic set of steps to capture something?
