What does the Window mode setting mean?
* window (default) - Flash will be placed on top of everything in "its own window"
* opaque - Flash will be placed within other HTML elements, it will cover everything what is underneath as per z-index order and will be
covered by everything which is higher as per z-index order
* transparent - Similar to opaque in terms of z-index,but everything placed underneath transparent portions of Flash will be visible.
