After looking at the Dr. Watson crash dump, seems to be crashing right
where the arrow (->) indicates. Also, when clearing the surface, you should use "ddsd.lPitch" to get to the next scan line.
Code:
SYSREDRAW:
        push edi esi eax
;       cominvk DDSPrimary,LockSurface,NULL,ddsd,DDLOCK_WAIT,NULL
        [*HERE*] -> cominvk DDSBack,LockSurface,NULL,ddsd,DDLOCK_WAIT,NULL  
        ;       DDINVOKE        WaitForVerticalBlank, lpDD, DDWAITVB_BLOCKBEGIN, NULL
    mov   edi, [ddsd.lpSurface]         ;--- copy vframe->video
    mov   esi, SYSFRAME
    mov   ecx, $c0000
    cld
    rep movsd
;       cominvk DDSPrimary,UnlockSurface,NULL
        cominvk DDSBack,UnlockSurface,NULL      

        ;cominvk DDSPrimary,Blt,0,DDSBack,0,DDBLT_WAIT,0
        cominvk DDSPrimary,Flip,0,DDFLIP_WAIT
        pop eax esi edi
        ret
    

[/code]

pabloreda: this doesn't cost you much. users don't see any difference. But instead, if there is an error and goes uncatched, your app will likely crash, and then users WILL see the difference
