Hi all,
just had the same issue as reported here - flight CYYC-PANC, in cruise FL300 tried to add the STAR for the alternate PAFA - selected the ILS 02L and when I selected the LIBER5 STAR the left CDU went black and the whole cockpit except the last two digits of the altimeters froze. Thrust, flight controls and gear still operated normal.
MXX mode was set to realistic. I hope the announced fix is addressing this issue.
Cheers
Michael
