Ok, just tried it.  As i can see there is some improvement here, along
with the following comments:

1/ When rebooting the system, the bad/old behaviour seems to happen
   systematically;

2/ When powered-off then powered-on, the behaviour seems to be more
   correct.  Nevertheless, i encountered the old problem more than
   *one* time... roughly ~40% to 50% :(
