Thanks a lot! I bought Oxygene anyway, after trying it. It works great on XP, but I get a bug on Vista.

I made myself a test with Managed DirectX that works, it was pretty easy to implement, I'm happy

You might be interested to know that PascalGameDevelopment has a subdomain related to XNA:

http://chrome.pascalgamedevelopment.com/

There are several examples.

But I can't run those, since XNA refresh requires VS2005 with SP1, and Oxygene comes with VS2008 I'll have to get VS2005, or wait until M$ gives support to modern technology.
