The air bubble was preventing the laser from tracking properly, and it was skipping back like a jumpy vinyl. The answer was to place a small piece of sticky tape over the bubble. This made the error big enough for the tracking not to be fooled by it and for the error correction to kick in properly. I prefer to save toothpaste for my teeth, and anyway, I use Colgate Blue Minty Gel, a) because the colour is like the background screen in edit.com, b) I like the taste, and c) it doesn't leave all those nasty gritty bits in your mouth. / | Mark P Edwards, | --------------- | 100325.223@compuserve.com | medwards@sound.demon.co.uk | Prestwood, Bucks.
