"The Speakeasy Speed Test requires the latest version of Macromedia Flash Player installed to use with your preferred browser.
Also, temporarily disable any Adblock extensions on your browser."
Running XP Home SP-2, all updates.
Some sites require one or the other to work. I go to Adobe and install the latest of each, and they both give the little animation that says they're installed. But they're not. In IE, Tools, Manage Add-ons, Shockwave Flash Object is listed as active, but nothing works.
Specifically this site http://www.speakeasy.net/speedtest/
My mirror machine and two laptops running XP Pro work. I do have the latest Java installed. Oh yes, I close then open IE. And it works perfectly in FF 2.x.
