However, "Andale Sans UI" is not available on all system. I guess "Andale Sans UI" will be installed with StarOffice. So it's not logical to be used as the first-priority default UI font.

I suggest we reconsider the use of this font and create a better font list that works more cross-platform and cross-locale.
