slider question

Hey, all-

I've been making some sliders based on Richard Calcutt's excellent tutorials here, but my boss is wondering if there's a way to get a slider to act more like a regular drag and drop-meaning that the slider itself would appear to follow the mouse, instead of having the jerky kind of optical illusion that you get with the sliders I've been able to make so far. I know that the more "states" you have on the slider, the less jerky it is, but it appears to me that any slider in storyline is going to have to rely on that same optical illusion. Am I correct? Is there a workaround that anyone knows about?

Any tips would be greatly appreciated!
