I have a list of locations that I am scrolling vertically in my movie with a mask over it (kind of like movie credits). My problem is when I try to loop the graphic it isn’t smooth. I am using the following script:

onClipEvent (enterFrame) {  
if (\_root.\_ymouse \< 768) {  
this.\_y --;  
}  
if (this.\_y \< -149) {  
this.\_y = 355;  
}  
}

It does work but, like I said it isn’t a smooth motion. I think I would need two of the same graphic and when one gets to a certain point on the stage the duplicate graphic should begin; then the first graphic should reposition itself back to the beginning and so on. If you have any suggestions I would greatly appreciate your help.  
Thanks
