Bug? Select muted parts on subtracks 1-4


I have a track which uses the new sub tracks functionality.

I have a tracdk with 4 subtrack, each containing some parts. subtrack 4 has the active part and also the others (1-3) are muted parts additionally.

I just got Cubase crashing by simply SELECTING the 3 muted parts in subtracks 1-3.

Anyone else?
