Yes, I've noticed that sometimes on first loading objects the scripts don't appear to respond. If I then subsequently restart dx everything works as it should.
Also I've noticed some strange behaviours on object deletion. If I choose yes to d e l e t e (excuse the spacing, WC seems not to like this word atm) related objects too, random objects in other groups mysteriously vanish. I have experimented with this, checked and dbl checked all depedancies, groups and parent/child relationships, object IDs and so forth, it just appears to be a gremlin.
