Isn't it, you know... illegal to call a game Vista compatible when it's not?
That's still not compatible if it doesn't work with the drivers that come with Vista,which most people do expect.

How much money would they open the source code for?
That's just what we've been trying to find out,but no-one seems willing to discuss the issue,or I've sent multiple e-mails about this subject,all of which I've received no answer to.
