[Gmsh] GUI fonts problem in Gmsh-2.2.3 (from binary package)

[Y.J. Liu]

Hi guys,

Newbie of Gmsh.
I downloaded latest (ver 2.2.3) binary package and found that it can 
import .igs and .stp geometries. That's great but, the fonts in the GUI 
menus and other (pop-up dialogs, etc.) are almost unreadable. (please 
refer to the screen shot below)

Is it possible to adjust the fonts, and how?

Thanks and regards,
Y.J.
