[texhax] Any PPCHTeX users out there?

[romeomedina at libero.it]

Hi. 
 
I subscribed to both PPCHTeX and Tetex mailing lists to ask for help, 
but they seem to be not active. 
 
I freshly installed tetex-src-3.0.tar.gz in my Mandrakelinux 10.1 Community 
box, in order to run PPCHTeX to type chemical structure formulas. 
Now, if I run TeX (onto a file containing PPCHTeX pictures) 
from within the directory /usr/local/teTeX/bin/i686-pc-linux-gnu, 
where the executable file `tex' is present, everything goes fine; 
instead, if I run TeX from my home directory, I get the message: 
 
! TeX capacity exceeded, sorry [text input levels=15]. 
 
Can anyone explain these two different behaviours and suggest how  
to work the problem out? 
 
Thanks indeed, 
Rodolfo
