XOR is useful for small scale animation and effects. I don't see your argument on RGB follows at all, but maybe you have a different use in mind. I also don't see that GDI+ offers a particularly appetizing alternative. The consequence is either to drop down to GDI (BitBltn etc) or put up with annoying flicker. XOR is built into the i86 language from day one, so it is hardly a patch to make use of it. I thought the essence of GDI+ was to make graphics simpler, more accessible, portable and consistent. A GDI+ style wrap for DirectX might be interesting, especially in regard to portability, but Microsoft should concentrate on making the existing product work before embarking on this feature. Your comment regarding Service Packs is intersting. Now that applications are built with Studio for a .NET framework, it is harder to know where the problem lies. But should I really care or distinguish? My job is to design product and cut code, not scour Microsoft's web pages for obscure patches. Incidentally the QFE you linked to was a rendering problem specifically for XP, and I have verified the same faults exist on all platforms. What Microsoft needs is a developer's page where we can report errors, have a tracking number assigned for all to see, and some progress indicator towards fixing the bug (and the SP in which the fix can be found). It's that simple. Maybe the boys in Seattle should send some coffee down to Redmond. Whoever makes the delivery should also administer a pointy boot to wake them up. But thank you for your comments. Now if only you worked for microsoft, we might achieve something! Only change is constant
