Hi

I’m adapting a pong flash game.

I’m having trouble moving a slider that controls the speed that the ball travels at - as soon as I move the slider (to the bottom  
of the game rather than the current right hand position) - and update the startDrag coordinates - the computer’s pong racket movement  
becomes erratic.

You can see the demo game here: [http://www.dirksmith.com/pong/pongTest.html](http://www.dirksmith.com/pong/pongTest.html)

Grateful for any help.

The scripts are:

slider actionscript on main timeline

onClipEvent (enterFrame) {  
/:drag = Math.round(\_root.diff.\_y - this.\_y)/ -10 ;

slider mc actionscript:

on (press) {  
startDrag(\_root.setter, false, 26, 65, 26, 140);  
}  
on (release) {  
stopDrag();
