Re: MOUSE_OUT not working on Mac

I guess it needs a mouseout event listener, that relates to the image on frame 1 and sends the button/movieclip back to frame 0 ...

so it might be worth trying something like
GalleryFrame_btn.addEventListener (MouseEvent.MOUSE_OVER, goBackF);
GalleryFrame_btn.addEventListener (MouseEvent.MOUSE_OUT, reSetF);
function goBackF (event:MouseEvent):void{
gotoAndStop(1);
}
function reSetF (event:MouseEvent):void{
gotoAndStop(0);
}

That's assuming that GalleryFrame_btn starts on Frame 0 with the dropdown closed, and on Frame 1 has the dropdown open ....
