i have the german localisation and when i change any of the fontsizes i always get: # # SCREEN & FONTS SECTION ############################ # \screen_dpi 75 \screen_zoom 175 \screen_font_sizes 5,00 6,00 7,00 8,00 9,00 10,00 11,00 12,00 13,00 14,00 i put in the values 5 6 7 8 9 10 11 12 13 14 in the textfields and saved the preferences. lyx saved all in european decimal style. in fact of the wrong comma lyx takes the values 5 0 6 0 7 0 8 0 9 0 for the fontsizes. i had to replace the comma with a point to get the right values.
