I had a similar problem with WinTexmacs 1.0.5 and i fixed it :

 

if i type

 

    (math mode) (x+1)^5,

 

the first bracket is big and the second becomes little because of the power ^5. Then i have to go to

 

   (menu)Format\Display Style\On

 

to have the good bracket size. I don't know why, but it works !!

 

Sincerly yours,

Can anybody find a reason why the delimiters in the attached file do no balance?!? 
 
In the .pdf you can see exactly what I see within TeXmacs (1.0.6.8) as well: The five expressions all are formatted as quantum mechanical ket-vectors, i.e. the | on the left and the > on the right are supposed to match in height in each case. All are formatted using <left|\|> resp. <right|rangle>. 
 
Either I'm missing something trivial or there is a really subtle glitch in the typesetter that never showed up before.
