Aero switching off bug will be fixed in Windows 7!
 

As most of you know when using the default rendering mode in BS Player on Vista it will turn off Aero theme.

But it looks like this will be fixed and not happen anymore in Windows 7 :)

Don't you hate it when a media application uses the video overlay function of your video card in Vista, and there's this annoying screen flash as you lose the Aero glass interface? Then there's another flash as Aero is restored when you shut the program down. With Windows 7 and WDDM 1.1 drivers, that shouldn't happen anymore.
