--- Comment #8 from Alexandre Julliard julliard@winehq.org --- FWIW it crashes because when it detects Wine, it skips the GetProcAddress call for UpdateLayeredWindow, but then calls the (uninitialized) function pointer anyway. They should just remove that Wine check, the layered window is working fine.
