Javascript nav dropping down over flash, and not intercepting mouse events

the nav drops down over flas开发者_C百科h elements that listen for mouse events. (ROLL_OVER) When the nav is in the down position over the flash, I would like to prevent the flash elements under the nav from receiving rollover.

This is not the same issue as the common, js/css nav dropping behind the flash. and Im using swfobject 2, & wmode:"transparent".

HTML elements on top of JavaScript is always a bit "shady". One solution might be using ExternalInterface with JavaScript, to tell the Flash element that it should be idle. So whenever the JavaScript navigation opens, execute a method on the Flash object which disables all interaction. When the JavaScript navigation closes, do the reverse.
