[PyMOL] label size

[Mario Sanches]

sorry if this question has ever been answered before but I couldn´t find it.
Is there a way to change the label size? I tried using ¨set 
label_font_id, 4¨, which gives me the biggest font, but it is not 
enough. Is there another way?

Another question, sometimes when I render some labeled figures using ray 
command pymol crashes with the message ¨segmentation fault¨. Is it a 
known bug?

Thanks a lot
