Hey, you guys were the ones who reported that MA3 worked fine with W7.
I've never even seen it.
I personally can't afford W7 at this time. Back when the Aquarium income was 10 times what it is now, sure. But not any more.
Actually, I'd have been happy to spend the rest of my life with XP. Works great for me, and DirectX 9c will probably be the last API I'll ever be able to develop on. DX10 and 11 use what's called Managed Resources, which is a nightmare. It needs an enormous DLL, which doesn't come with the Operating System.
