Map won't load

I recently started using the Opera browser instead of FireFox. When I try to view the map at http://www.arednmesh.org/content/aredn-map-0 I get a "Error: data not loaded" msg instead of the map.

I can open the page that's framed (http://usercontent.arednmesh.org/K/5/K5DLQ/livemap2.html) no problem. It just won't display on http://www.arednmesh.org/content/aredn-map-0.

Anyone know how to fix this short of using a different browser? Thanks.
