Let me put it this way, to make a game compatible with another OS (Vista) would take time, money, and programmers.  Hence why many companies haven't made games compatible with Vista, it would cost more money then they would make.  Such as this, 1 out of some odd million users has an issue with the game and Vista, so does it make sense to hire programmers to make the game compatible?  No, it would simply put a company further back regardless of the amount of money they make.

Fly or Die can update to use Windows Vista the Tech's need to do it all they have to do is do it and if they can not show me why I'm not a person that does not know about what can be done and by who computers have i my life more years when they were Side by Sides Tapes and Punch Card. They can do it by writing a New Program

Vista is terrible for games, even Java based games.  I would go back to XP, a more solid OS.

Whilst it is true that almost all new pc's now come with Vista pre-installed, it is also true that many major gaming providors (Maxis, Blizzard etc) has point blank refused to provide support for Vista.

Even Microsoft themselves have been forced to provide users of their more expensive versions of vista with the option to get rid of it in favour of a previous Operating system.
