Parallax Scrolling & Buttons

Howdy - This forum has some great references & info on Parallax - wild stuff! I added some parallax movement to a map I developed that has buttons to point out what the various buildings are and what’s inside, etc. What I’m finding is that when I load an external .swf from one of these buttons, the whole background is still controlled by the mouse-movement. Is there a way to stop the scrolling action behind the loaded .swf; and once that .swf is closed, the scrolling-fun continues?

Here’s a link to the example:

Also, how would I set up a stationary legend for instance, where one clicks on “base lodge” and the map automatically moves to that area of the graphic?

Thanks very much for any assistance!
