Slide in/out on mouse in/out

hey guys,
first and foremost, this is my first post :slight_smile:

anyways…

i am writing gallery, and i would like to have a small control bar with next/previous buttons. that is “easy”; i have created a movie clip with 2 buttons in it. the problem is that i am trying to make that movie clip invisible unless the mouse is inside the swf.

in the gallery made at http://www.slideshowpro.net/, you can see that whenever you mouse in there is a white overlay that slides in at the top, and slides out when the mouse moves out - everytime

right now i can get the “control” movie clip to slide in properly, but it won’t ever slide out.

and on a side note, is it normal if


onClipEvent (enterFrame)	{
	  trace(_root._height);
}

outputs the height of the current movie clip and not the swf? i only have one movie clip on the stage.

Thanks in advance :slight_smile:
