rotary-movement: Fire up paint. Try to draw 5 perfect quarter circles. And then ditch that idea completely and forever. The only special cases where rotary movement works is multi-touch screens or in a limited why when your "mouse" is a track-ball. Make it look like a rotary, make it usable like a slider (that is up/down _or_ left/right movement). And if you really need to save space: Use it like a slider, paint it as a color-field with the value as number and color... Have fun, Arnold
