Flash Player 10 - Context Menu not working on Embedded Video

A simple problem: Place an embedded video on stage. Customize context menu using ContextMenu class (flash.ui.ContextMenu). ContextMenuEvent.MENU_ITEM_SELECT event won't fire when you right click on embedded video. Just click on anywhere without video, it will work. If you place a rectangle over the video with 0% alpha fill , it will start working even on the video. This happens with Gaia framework, but i think this is a flash player bug.

I didn't google if someone else having the same problem or not. Just an unimportant experience.
