I placed all my major items exactly where I wanted them then locked them. The zero reference point was set to one of them.
Come back to editing today and some, but not all, of the locked items have moved by 10mils ! The zero reference item is still at 0, -0.001 so it hasn't moved.
Unlocked items seem mostly to be in the same place.
What's happening ?
Brand new interactions and interfaces. 
Easy to use and quick to get started.
