.net-4.0-rc1

I get an exception thrown at runtime when I set AllowsTransparent="True" I get an exception saying the WindowStyle can not be set to None if AllowsTransparent is set to true. Even if I explicitly say that WindowStyle is set to SingleBorder I get this error. However, if I set WindowStyle to SingleBorder and remove the AllowsTransparent-tag, I get no error, and the top of the window (the icon, name and close, minimize and maximize-buttons) disappears. Anyone knows what can cause this? Or is it just a bug in .Net 4.0 rc?
