thank you for yours advice

I am assuming you are using Windows 7 for this. When you are in your interface, there will be a green polygon button at the top. Click this. Drag out the area you want, and then on the last point, double click to close it off. Match the new polygon to your fence you have hopefully already placed. Then, click ONCE on your polygon. Then right click the polygon. Click "Edit Object". This will bring up your menu that your looking for. Click "Ok" when finished. Then right click the polygon again, click "Move To Back" and than your good to go! Hope this helps!

Also airport background polys are not available for FS9
