I've got a SWF that's embedded in a VF page.  I've set the layout that houses the VF page to be a one-column layout and the page has nothing but the swf embedded in it.  the swf itself has only a form wrapper around the google map.  Why doesn't the Map extend the width of the screen?

<apex:page standardController="Location__c" extensions="GoogleMapManager">
		<apex:flash id="flexSOs" src="{!$Resource.FlexGoogleMap}" 

			height="100%" width="100%" 

			flashvars="session_id={!$Api.Session_ID}&server_url={!$Api.Partner_Server_URL_150}&aLoc={!latitude}&zLoc={!longitude}"/>

</apex:page>
