Thank you Christophe,
I really had no idea what to do with all these t1 and t2 ;-)
Apparently the bad settings of VW are due to the mac version (bouhouhou, why
is it so hard to work with so excellent machines ??!! and worse with the
macintel for which there is no VW release, whereas it is the more robust,
powerful and nice-looking computer I have ever seen :-( ).
Anyway, thanks again !
Paul
