changing the font in the navigation pane

[simonjarvis]

I know this is probably a silly question but does anyone know how you change the font size used by outlook (2003 running with win xp) in the navigation pane (ie. the folder list that you can show and hide by pressing alt+f1).

Is it a windows appearance thing or a setting in outlook? I can't find it anywhere & it's making me nuts.

Thanks for your help.
