[NTG-context] A solved problem

Hello Just a message to explain a problem I had and the answer. The trouble : the big parenthesis were not big, $($ and $\bigl($ gave the same shape The fix : I defined my own environment in which I defined very big font sizes. \definefontsize[e] \definebodyfontenvironment [default] [e=4] One of them was \definefontsize[g] I changed it to \definefontsize[gg] and all went right again The explanation (?) : maybe \big was read \bi (bold italic) with size g ???? I had this problem for 2 years, I'm happy to have figured it now. -- Eric Détrez Informatique Lycée Faidherbe, Lille http://eric-detrez.fr
