[COOT] stuck with black fonts

[Andrea PICA]

Hi everybody,

I am using coot (version 0.8.1) on a linux debian system. Atom labels 
are shown in black and on a black background this is not ideal. 
Unfortunately changing the color in Edit>Preferences>Others>Fonts 
doesn't seem to work (color is always black even if I select a different 
one). How can I solve this issue?

Thanks,

Andrea
