Hi iam using following code to scroll map. when scrolling horizontal or vertical, it scrolls perfect without any jerk(stutter) but when scroll diagnol this stutter happens.

```auto

function scrollMap(){
 var p = {x:0, y:0};
 var minX=(stageW/2)-32;
 var maxX=(stageW/2)+32;
 var minY=(stageH/2)-32;
 var maxY=(stageH/2)+32;
 myAvatar.localToGlobal(p);
 if (p.x<minX) {
  if (avatarMC._x<-walkSpeed) {
   avatarMC._x += walkSpeed;
  }
 } else if (p.x>maxX) {
  if (avatarMC._x>-areaW+stageW+walkSpeed) {
   avatarMC._x -= walkSpeed;
  }
 }
 if (p.y<minY) {
  if (avatarMC._y<-walkSpeed) {
   avatarMC._y += walkSpeed;
  }
 } else if (p.y>maxY) {
  if (avatarMC._y>-areaH+stageH+walkSpeed) {
   avatarMC._y -= walkSpeed;
  }
 }
}

```

any help?

Thanks in advance.
