This might be a problem in DialogBoxParamA

0021:Call user32.DialogBoxParamA(00400000,00000068,000401f8,004bd890,00000000)
ret=004bdd3e
0021:Ret  user32.DialogBoxParamA() retval=00000000 ret=004bdd3e

MSDN states:
If the function fails because the hWndParent parameter is invalid, the return
value is zero. The function returns zero in this case for compatibility with
previous versions of Microsoft Windows. If the function fails for any other
reason, the return value is –1.

If change return value to -1 instead of 0, it doesn't crash anymore, prints a
d3d fixme (so it get's further) but then seems to hang. The icon is in the
taskbar, and ps -ux shows the program runs, but i can only see a black screen.
