[XeTeX] warning: XeTeX & broken typescripts (please wait with upgrading)

[Dalyoung Jeong]

Dear Mojca,

I read your warning on ConTeXt update for XeTeX users.
I also have font problems after update. After all, I stick to the  
version in Jan.
It worked fine, in general.

I have a few questions.
I still have a font problem in mathematics. Greek letters and some  
math notations are not appeared. I didn't define math fonts in  
typescripts file.

Is there a way to  make greek fonts appeared in mathematics?

best regards,

Dalyoung
