Weird. on Win7, 7.43, I only have '9' available in the list for fixedsys, same on 6.35 actually.
Anyway, you can use the /font command to manually set the font
/font -z -12 fixedsys would reset all the fonts to that settings
my tired eyes thanks you!!
this command would set all the windows to fixedsys 11 size font?
