thanks for all the help, greatly appreciated. I'm not as concerned with the spring back but rather that it plays over itself leaving a trail. Right now, as I move the mouse it doesn't play throught the circle animation until I stop and the function stops refreshing itself. I thought maybe I could change the displace if i>10 etc. but no luck. Just to much for me right now. Do you know of any tutorials that might help explain this. I'm gonna try to read through guy's posting on the macromedia sight. might shed some light for me, anyways...
