Vista screen display - different from XP?

I am hoping that someone can tell me whether MS Office programs display
differently in Vista than in XP, specifically the Office 2007 beta
programs.

The reason I am asking is that I am writing a book on Outlook and have
been taking all my screen shots in XP. The publisher suddenly decided
that the book's figures should have the "Vista look" but I do not want
to redo them if I don't need to. The screen shots show only the program
window itself or program dialog boxes, never the desktop or other non-
program stuff.

Thanks,
