request for windows test ddraw/dsurface

[Marcus Meissner]

Hi,

I am suspecting that in IDirectDraw1 the behaviour
regarding backbuffer creation might change if we have
a just created frontbuffer of the same size.

(This is similar to behaviour shown by bulanci.exe
of http://bugs.winehq.org/show_bug.cgi?id=9008 )

Can someone please try this on Windows please?

Ciao, Marcus
