Mark, That is generally how these specs are implemented. Event dispatching is a feature of the virtual machine that is Flash Player, it's not a framework level concept. The same is true in browsers, etc. Any feature of the virtual machine is implemented in native code with only an ActionScript definition to link against. The native code in the player executes the event logic much, much faster than the ActionScript equivalent. It's been a long time, but somewhere around early Player 9 we did a simple test to see what this movement to native code actually bought us and I believe the results were a staggering 25-30 times faster than could be implemented in AS. Considering the gobs of events Flex dispatches, that change is _part_ of what made Flex 2 viable from a performance standpoint over the Flex 1.x versions. Mike
