Why is my RibbonWindow not themed correctly?

Question

Working with the ribboncontrolslibrary, when I run my application the title bar looks like W98 application,. How can I make it look pretty?

Edit: It seems that has something to do with the theme used on windows.

any help would be appreciated.

(from my previous comment)

You can draw a custom window frame as described in this MSDN article: http://msdn.microsoft.com/en-us/library/bb688195(VS.85).aspx, which includes information about drawing the window caption with the system theme's font (which might provide clues about accessing other theme information).
