Fix for Flash "Click to activate object" behavior
In response to a recent patent suit that Microsoft lost, they released an update that changes IE. The update causes items in object tags to require a click to activate. The most obvious time you'll notice this will be with Flash files. In the case I ran into, the Flash file still loads, but when the mouse hovers over the animation an outline appears around it and you see a tooltip with the message "Click to activate and use this control". Here's a
thread about it with a fix that seems to work, at least in my situation. The post near the bottom of the page has the best explanation of what to do.
