Real Player & Flash
There is a big empty white space where it used to be. I'm running Firefox 13.0.1. I've got no popup blockers running. I've fully updated Flash and the maps are gone! The maps show up and operate just fine in IE.
I had this same thing happen & I did not have to roll back the flash player. After reviewing the Firefox solution, I followed their suggestion & it worked quite well. If you don't have Real Player installed, then I don't know what to suggest.
As I indicated, I still have the latest flash player. Here is what Firefox suggested:
Go to Real Player and click on the upper left icon. Then, click on "preferences". Click on "download & recording." Next, uncheck "enable web download & recording."
This worked for me, but you can surely review the solution in Firefox. When this was malfunctioning, it would not play You Tube Videos either. Now, the nationwide map is back.
