[Bug] Edit in Wavelab from Nuendo 7.1.35 to 9.5 does not work

Wavelab will open but will not open the selected file in Nuendo.

Works as before here, Nuendo & Cubase.

Maybe a mac only bug then?

Okay, I have tested again.
It’s strange. Sometimes it works, sometimes it does not.
I can’t find the reason behind the erratic behaviour.
