Changing the user interface font
There is no dedicated option to just change the font in the User Interface in OpenOffice.org versions that are based on the 641 builds (including OpenOffice 1.0). Nevertheless it is possible to change the font by the general font replacement mechanism. Select
Tools -> Options -> OpenOffice.org -> Font Replacement
from the menu. Check the “Apply Replacement Table” check box. Replace the font
Andale Sans UI
with the desired font. You probably will not find “Andale Sans UI” stated in the font list box of the font to be replaced but you have to write it manually into the “Font” field. Please choose one of the fonts from the dropdown list box for the “Replace with” entry. The settings apply immediately after pressing the “OK” button.
