Images keep going off the screen

Hi,

I have created a simple card game and added motion tween to it, the cards move around in a sqaure but they go off the screen and come back on because when i run the swf file, the window is to small, if i make the window bigger it still does not keep it on the screen. so it will go down off scren then back up on screen.

I wanted to knrow if i could set it to automticlly set the window so that it does not go off screen.

Thank you
