回答1:

On Vista and Windows 7 you will need to disable Aero for the code to work.

Take a look at the answer I provided to the following question How to add an extra button to the window's title bar?

I don't know if it is possible since you can only edit the text but not the markup.

I think it just uses the font-size that windows uses...
