Yes, go back to the .fla file and remove the getURL.
If you can’t do that, then you’ll need to use a combination of HTML and CSS to “cover over” the <div> containing the Flash. This in effect, blocks the clickable part of the Flash.
First, be sure that your Flash has a window mode, like “opaque”, like yours does, but that’s a critical part.
<param name="wmode" value="opaque"/>
Second, create a transparent .png and place it in a <div> absolutely positioned over the top of the <div> holding the Flash. You can do this in PhotoShop by creating a .png of any color, and then setting opacity to 0%. Then put that image in a <div> over the Flash. Here is a simple test of the CSS I used to test this process.
