    The Window css seems to be downloading BOTH the gif and png sprites....if they both contain the same elements, that seems a bit redundant (and perhaps why the window seems to "pop" in)?

    So should the icon be it's own image?  Therefore it won't be downloaded if we don't even use the default window icon?

    (validated this on the demo site)

    Hi Steve,

    This is needed because of the shadow implementation (EnableShadow=true). When a RadWindow is set with that property, it uses the PNG image in order to provide semi-transparent, rounded shadows. When that window however, is set inactive (e.g. when you click on another window opened on the same page), it starts using the GIF file instead as the transparency is not needed at this point. This is happening only if EnableShadow is set to true. If it is set to false, only the GIF is downloaded.

    As for the icon image, it is placed in the sprite for convenience. Even if we remove it from the sprite, its size will not be significantly reduced.

    Best wishes,
