I absolutely can't believe it. At the exact time Jerry was struggling with this, I was working on *exactly* the same issue. Couldn't have phrased his question any better - I was actually looking in /dev for a "one" device! My way of resolving the problem, BTW, was to create a pure white bitmap in PhotoShop and trim it to the size I needed with "head". Different ways to skin the cat! ;) KeS
