problem with lyx-code

[monty]

Some people has asked me for a small effect not desider when they write a "n"
after a blankspace in the enviroment lyx-code with language Spanish. The fact is
that when they do the ps, the " n" become "ñ". 

I've tried the same, but i don't suffer this effect, while other four people do.
The example they gave me is attached.

Any idea?
