Hi Jari,

yes strange this wanting Greek letters. Does not appear everywhere, but only on some stars.
I also noted that there issome link to "constellation labels" in user data sets.
if you change the font color for "constellation labels", the font of the star names also changes.
(Helpfull, if you have a black or nearly black sky background, because the original font of the star names seems to be black).

Regards
Roger
