It appears to be Gabriola, which Microsoft introduced with Windows 7:

http://www.microsoft.com/typography/fonts/family.aspx?FID=372

I followed the second link to the Monotype site (which sells most of the Microsoft typefaces), but it doesn't appear to be listed. Identifont.com states that it isn't available for sale.

Wow thanks!
Done!
