How could you notice that?

You're lucky then…

No, not yet. But I'll make a try.

Sorry, but I never pointed that out :-) Actually, I don't know  
anything about that… I only made test files after the installation of  
the LM OTF fotns, that is to say two different (short) document, one  
for each (TextEdit and NeoOffice) and then noticed their behavior…

Thanks for your explanations,
