Seems that you have resolved the issues meanwhile. The program I suggested didn't use GDI+ AFAIR. I played around a bit with GDI+ myself and from what I've seen there's no need for pre- alpha multiplication, when you use the GDI+ drawing routines. Don't know if it's needed when combined with old GDI-routines, though. Anyway, in my brief tests here pixel blending looks fine. Thanks again for your efforts.
