videoClip does stop playing????

[Ban Nguyen]

Hello,

I have a video (.mov)

I create a button (play) with this code:

on mouseUp
   play videoClip "my movie"
end mouseUp

I also create another button (close) with this code:

on mouseUp
  close this stack
  stop playing videoClip "my movie"
end mouseUp


The problem is:  the stack is closed but the video still play (you can
here it)

I don't know any other command to stop the video.  Please help.  Thank
you
