hi all,

(sg36.sdg,sg36.sdv,sg36.thm). I use OpenOffice open the three file, but I can 
not understand the file (I only can see the binary code).
  What tools can do this? Can you tell me? I want to change the word used in 
the fontwork gallery ,for example using "font" instead of "fontwork".How can I 
do this?
