No scrap that last message, my original trace was incorrect.
A typo meant I was outputting the size, not the flags :(

The flags are actually 4103 which includes DDSD_PIXELFORMAT.

Back to the original situation.

So, what is happening is that the caller is specifying DDSD_PIXELFORMAT 
but there is nothing in the DDPIXELFORMAT structure to indicate how to 
render.
However, the surface pointer is NULL so there is nothing to actually draw.

I added some code to test the PIXELFORMAT structure and if didn't like 
what it found, it inserted the default.
It gets a lot further but crashes later on. I will try and find out what 
is happening then.

Cheers,
Ralph
