[MX] _root.drag question for you masters

I am loading a scrolling image bar into a seperate movie and it works great with the coding I have managed to piece together(since I am not an AS master) the problem I am having is that when the mouse moves out of the scrollbar area it is still controlling the motion from the rest of the movie it is imported into. I am pretty sure that it revolves around a _root.drag._y script command but since I am still learning scripting I am not sure of exactly how to code this…the scrollbar is 90pixels in height and I want the images to keep scrolling at +2 when the mouse leaves the designated area, just not to move with the mouse movement when moving around below the scrollbar.

here is the code …if anyone can help out that would be WONDERFUL…thanks for the help…JK

mc = _root.drag._x
if (mc>250and mc<360)
{
for (i=1; i<=nomc; i++)
{
mx = getProperty("/a" add i, _x);
setProperty ("/a" add i, _x, mx+2);
}
}

if (mc>440 and mc<550)
{
for (i=1; i<=nomc; i++)
{
mx = getProperty("/a" add i, _x);
setProperty ("/a" add i, _x, mx-2);
}
}
