I’ve got big projects. When I select many containers at once I’ve got crashes with Cubase. It happen randomly in projects and on some projects it always crashes on a specific few, Doesn’t happen when I select one at the time,
Also, often if I move/Alt-copy drag a container to another midi track it crashes on the release. That one also happened to me numerous time. Never happened before on earlier versions of Cubase.
It might be a memory problem as maybe Cubase has harder time allocating on bigger project.
