I have lost Vista's Aero theme.
My computer is a gateway laptop, purchased in May 2005. I have been part of the Longhorn/Vista beta since late July 2005 (when B1 released). My video card has displayed Aero, on EVERY build. ATI has it listed as being compatible with Vista since day one.
BUT, I have just installed Vista RC2, and It does not display. Heck, it doesnt even give me the option! I have updated to ATI's RC1 drivers (as those were more recent than the ones installed during Vista's installation.

Where I choose the theme, it doesn't even give me the option. Any clues on what to do?
PS: I love the snipping tool.
