After loadMovie ("image.jpg", instance); action onRelease doesn't work

After I loaded a .jpg with loadMovie I want to attach a onRelease action on that movieclip but I can’t make it work. If I make the loadMovie action inactive the onRelease action is working fine but the image will not load in the mc and vice versa.

Code:


// load the .jpg
loadMovie ("image.jpg", button_mc);
 
// add onRelease action on mc 
button_mc.onRelease = function () {
trace ("test");
}

Thanx in advance for any help
