I had guessed that it downward expanded slow movement, too, but I never really dug into it to see for sure. There is the mouse speed slider, too, though, which scales the velocity linearly, which could "damp" the motion in a different way. > There's no point in smoothing mouse input, really; unlike most input > devices, mice don't have any appreciable noise in their output. All the > smoothing does is make everything feel laggy. I wonder, though, if the input is noisy but is sufficiently filtered by the software path. I mean some of these mice claim 1000dpi, I can't imagine they're not going to have some jitter at the hardware sampling level. -tom! -- ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
