Problem with loadMovie and on(rollOut)

1

Having an issue with the code below on my buttons. The buttons are a map of buildings in a city. Rolling over the buttons loads an external .jpg into pic_mc. The problem arises when the user rolls quickly over several buttons. From what I understand about loadMovie, the .jpg takes some time to load, and the load completes after the on(rollOut) event. When the load completes it wipes the _visible property from pic_mc, leaving the image visible when the mouse is not on the button.

Is there a way around this?

swf is here

 on(rollOver){
	bg_mc._visible=1;
	pic_mc._visible=1;
	pic_mc.loadMovie("bank400.jpg", 10);
	bg_mc.address.text = _root.bank400_address
	bg_mc.use.text = _root.bank400_use
	bg_mc.own.text = _root.bank400_own
	bg_mc.notes.text = _root.bank400_notes
}
on(rollOut){
	pic_mc._visible=0;
	bg_mc._visible=0;
}
