Ann,

See the Infowindow documentation here:

http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/components/supportClasses/InfoWindow.html

The show function is what you need and all you supply is the map point you want to display the point at.

            private function mClick(event:MouseEvent):void
            {
                var gra:Graphic= event.target as Graphic;
                map.infoWindow.show(gra.geometry as MapPoint);
            }

Don't forget to click the Mark as answer check and to click the top arrow (promote) as shown below:
