Hello,
I just upgrade LE from stable version (8.2.5) to latast beta (8.90.008).
Everything seems to work fine except the power off menu, if I press "Power off system" the box reboots, the same happend if I press "Reboot".
I finally managed to power off the system with "Suspend" option.
"Power off" option was working properly before the upgrade.
Best regards,
Lukeid
