there is a problem with the brackets in the math mode : when i type something like (x+1)^2 or [x+1]^2 or {x+1}^2... the second bracket becomes a little one. So you have a big and a little bracket !!!

 

To be more precise, when i have just typed (x+1) the two brackets have the same (big) size, but after i click to the "exponent button", the second bracket changes it size !!

 

(i use WINtexmacs)

 

best regard,
