Hi Karim,
Yes, the student told me she installed OM 6.16.
Now she has installed Ubuntu on her laptop, but this morning I have received a her mail saying that as alternative solution she could run Win 7 from a usb pen, so to use OM in that OS.
Unfortunately at the moment I have not had the possibility to assist her more directly, so I hope I am exact in explanations and news. I will give a more exact feedback as soon as we can get in touch in our Institute.
Meanwhile many thanks to you all for support.
Ciao
Fabio
P.S.
Only for sake of clearness: the problem started because this student is the only person of the course (composition for didactics) to have a tablet, an Apple one I suppose, so she recovered an old computer for following the course using OM.
