It blocks Opera... then tells you how to get around it. Why not permit it in the first place? Well, it doesn't work perfectly with Opera. I was unable to drag the signs past the no-entry sign - when dragged, they only showed up at the top of the window as I dragged the mouse down towards the taskbar. Wouldn't it be better to redirect it to a page that says, "Your browser may not support this app. Click here to try it anyways"?
