I’m still pretty new to AS3 and here’s one of those problems that i kept avoiding to confront, but I’ll finally ask for help.

I’m creating a video player and i want the interface (controls etc) to show up only when you roll over the video. i tried adding an event listener to the video object but ti wont work, so i added a transparent bg. to the controls, made it as big as the video, and added an event listener to that.

It works good except one thing: when i roll over a control, it triggers the MOUSE\_OUT event, and the controls hide… i’m guessing it has to do something with event propagation.

Could anyone please help me out?

Very appreciated,
