Wavelab ARA editing always chrashes Nuendo

Hello,

My Nuendo/Wavelab odissey goes on:

Any time I try to edit a wave in Nuendo with Wavelab (ARA), after 5 or 6 waves edited (No special operations. Just simple editing), Nuendo crashes.

Is there something I could check?

Thanks in advance

Dario

PS. MacOsX 15.7.4 - Nuendo 14.0.41 - Wavelab 13.0.10
