Display (menu) layer over Flash object
Is there a way for layers to be visible over a Flash object? It appears that the (menu) layers load below the Flash content, making them unreadable.
Flash objects normally appear above all other objects on the page, including (menu) layers.
The solution is to make the Flash movie's background transparent using the WMODE tag. This will allow the DHTML layer underneath the Flash movie or layer to appear. You can use the "wmode" parameter to set the transparency.
