Im using fluxbox Space,why cant i remove Anti-Aliasing or Hinting,after i apply the settings they back on again.

this is a bug in lxappearance. You can check /home/user/.gtkrc-2.0 and see if the changes stick. You are looking for the lines gtk-xft-antialias=0 (for off) and gtk-xft-hinting=0 (for off).

lxappearnce does change the values, but the check marks come back everytime in the gui.
