on the first run it "deshakes" for 38 frames (and saves the values) on 2nd run (the visible on) there are 45 (correct length) frames. how can the first (false length) run be prevented, else the vector data are not correct ? i had also a first run with 45 frames (a lucky moment) , then it will work perfect. regards marco > > -- > +-DRD-+ > > ------------------------------------------------------------------------------ > Get a FREE DOWNLOAD! and learn more about uberSVN rich system, > user administration capabilities and model configuration.
