Web Player Coexisting in Browser Window

Unity Web Player behaves differently than players like Flash or Shockwave. For one thing, Unity content does not show up if the browser window is printed.

It also looks like Unity can’t share the window with an overlay like Lightbox, at least on some browsers. I’ve been trying a Lightbox clone, Floatbox, and found that it only works properly in Safari – the window dims and the overlay appears over the Unity player. Firefox mostly works – the window goes black before the overlay appears. But in IE, the Unity player goes away before the overlay appears, and then gets loaded again when the overlay is closed. Not usable.

Does anybody know if there’s a workaround for this? Is there anything comparable to Flash’s wmode? Is there any reason for the Unity player to work differently than Flash? Is there any reason for it to work differently in different browsers?

Flash runs in 2D on cpu and can be rendered by the browser. Unity is purely hw accelerated and can not exist inside the browser (at least not most, there are some, primarily webkit based + FF4, which render with hw acceleration too - those are the ones where the overlay normally works as well - if you are on a 2D browser, you won’t get anything but iframe in front of the unity webplayer no matter what you do, at least out of my experience)
