How to set the Latex equation editor
HI,

I am trying to set the Latex Equation Editor but i can get it working properly.

The problem is: The fonts do not display properly e.g $A \to B$ shows "A B" and the font is not right.

I have:

-- updated to the latest Mactex distribution and made Tex fonts available to all mac aplications.

-- i wrote the same lines i have in Texshop, which work properly.

-- I updated my binarytree using texhash in terminal

But still The equation editor does not work

Could anybody help me.
