Hi Allocator,
i was in a wrong way ... thanks you.
but i have also some freezing problem, not easy to detect:
one time RB goes very slowly with no display for the flight graphical
but OK on the interface !!! and after withe screen (and i have loosing all
the data ...).
i read the informations on the forum and there does not seem of be a link
with internet.
Regreatably freezing took place when I was not in front of my computer,
so it's difficult to have a diagnostic for help AirNav.
